The following section is addressed to those of you who would like to edit those configuration settings that could not be modified with the help of the GUI (Graphical User Interface) of the LimeSurvey installation. Please bear in mind that all the changes from the LimeSurvey root directory are done at your own risk. Nevertheless, in the case in which you are experiencing problems/need further guidance, join the discussion forums or the IRC channel for help from the LimeSurvey community.


To modify the configuration settings of the installation, you have to edit the optional settings. They can be found in the /application/config/config-defaults.php, which is located in the LimeSurvey root directory. The default settings of the standard installation can be found in config-defaults.php. Some of them can be overridden by using the global settings dialog, while the others will have to be manually edited.

Wenn Sie diese Einstellungen zu ändern möchten, ändern Sie bitte nicht in config-defaults.php, sondern kopieren Sie die jeweilige Einstellung/Zeile nach /application/config/config.php in 'config'=>array() und ändern es dort.

Alle Einstellungen in config.php überschreiben die Vorgabe-Werte der config-defaults.php und einige von diesen werden von den Globalen Einstellungen (Neu ab 1.87 ) überschrieben. Auf diese Weise ist es viel einfacher Ihre Installation zu einem späteren Zeitpunkt zu aktualisieren!

When an upgrade occurs, only the config-defaults.php settings are changed. Therefore, editing the config.php file will save your customized settings.

To update/add the LimeSurvey settings in /application/config/config.php, you have to update the config array:

        'LimeSurveySetting'=>'New value', // Update default LimeSurvey config here

Yii settings

LimeSurvey uses the Yii framework, which has its own configuration parameters in the application/config/config.php file. You can also access some specific configuration settings of LimeSurvey via the Yii configuration.

The Yii specific settings are set in the components array:

    'components' => array(
        'db' => array(
        'Specific settings'=>array(

Note 64x64 bubble lime.png For more information about the Yii framework, please access the following link.

Database settings

The database settings are written to config.php by the installer file when you install LimeSurvey for the first time. If needed, you can update this part of the config.php file. Please remember that you do this at your own risk! See also the Yii documentation and please remember that LimeSurvey supports only the following types of database: mysql, pgsql, dblib, mssql, and sqlsrv.


Sie können einige Sitzungsparameter in config.php setzen - das erste Beispiel ist die Sitzung in der Datenbank. Sie können den Teil in config.php auskommentieren/hinzuzufügen wenn benötigt. Siehe [Yii Dokumentation] für weitere Einstellungen.

Wenn Sie SSL ("https") für Ihre LimeSurvey Installation nutzen, können die folgenden Zeilen in Ihrer config.php die Sicherheit erhöhen:

        // Setze den Cookie via SSL
        'session' => array (
            'cookieParams' => array(
                    'secure' => true, // use SSL for cookies
                    'httponly' => true // Cookies dürfen nicht von anderen Protokollen genutzt werden

Wenn Sie die Domain für einen Cookie setzen möchten, setzen Sie dies in config.php:

        // Set the domain for cookie
        'session' => array (
            'cookieParams' => array(
                    'domain' => '',

Request settings

The request settings are important, but the default settings are already optimized for LimeSurvey usage. To read more about them, see the Yii Documentation.

For example, the LimeSurvey request settings configuration may be modified in the following way (at your own risk) :

        // Disable CSRF protection
        'request' => array(
        // Enforce a certain URL base 
        'request' => array(
            'hostInfo' => ''  
        // Set the cookie domain name and path for CSRF protection, path is used if you have different instance on same domain
        'request' => array(
            'csrfCookie' => array( 
                'domain' => '',
                'path' => '/limesurvey/',

If you need to update only the url for token emails, set your publicurl in your config.php file.

URL settings

To change the default URL settings, update the urlManager:

       // Use short URL
		'urlManager' => array(
			'urlFormat' => 'path',
			'showScriptName' => false,

You can also add .html after the survey id in the following way:

       // Use short URL
		'urlManager' => array(
			'urlFormat' => 'path',
			'rules' => array (
			    '<sid:\d+>' => array('survey/index','urlSuffix'=>'.html','matchValue'=>true),
			'showScriptName' => false,

For more information, check the Yii documentation.

Logging settings

Yii provides different solutions to generate logs. To find out more about them, check the logging special topic. LimeSurvey uses '1' or '2' by default, which allows every web user to see the logs. You can create your own settings using Yii directly.

For example, a quick solution to log errors and warnings in files is:

       // Log error
'log' => array(
    'routes' => array(
        'fileError' => array(
                    'class' => 'CFileLogRoute',
                    'levels' => 'warning, error',
                    'except' => 'exception.CHttpException.404',
Hint: The file is saved by default to limesurvey/tmp/runtime/application.log, which is located in the LimeSurvey root folder.
Yii uses runtime path. By default, the logs are web accessible. They may contain a lot of information from your server. It is better to use a directory that cannot be accessed via the web. You can set it in routes or by updating the Runtime path.

Runtime path

The runtime path must be a readable and writable directory for the “web user”. However, the runtime path contains files with potential security information that are located in the public web access area. LimeSurvey collects these files in the temp directory of the LimeSurvey root directory. In order to eliminate the access to such important data, you can set the runtime path outside the public web access by editing the respective lines in the /application/config/config.php file:

return array(
  'components' => array(

Generelle Einstellungen

  • sitename: Gives your survey site a name. This name will appear in the survey list overview and in the administration header. The default value is 'LimeSurvey' and it can be overridden in the global settings dialog or edited in config.php.
  • siteadminemail: This is the default email address of the site administrator and it is used for system messages and contact options. This setting is used only as default value and can be overridden in the global settings dialog.
  • siteadminbounce: This is the email address where bounced emails will be sent to. This setting is used only as default value and can be overridden by the global settings dialog.
  • siteadminname: The real name of the site administrator. This setting is used only as default value and can be overridden in the global settings dialog).
  • proxy_host_name: This is the host name of your proxy server (it has to be mentioned if you are behind a proxy and you want to update LimeSurvey using ComfortUpdate).
  • proxy_host_port: This is the port of your proxy server (it has to be mentioned if you are behind a proxy and you want to update LimeSurvey using ComfortUpdate).


  • maxLoginAttempt: This is the number of attempts a user has to enter the correct password before he or she gets her or his IP address blocked/locked out. The default value is 3 and it can be modified from config.php.
  • timeOutTime: If the user enters the password incorrectly for <maxLoginAttempt>, she or he gets locked out for <timeOutTime> seconds. The default value is 10 minutes and it can be modified from config.php.
  • surveyPreview_require_Auth: Set to true by default. If you set this to 'false', any person can test your survey using the survey URL, without logging in to the administration panel and without having to activate the survey first. This setting is a default value and can be overridden in the global settings dialog or edited in config.php.
  • usercontrolSameGroupPolicy: Set to true by default. By default, non-admin users defined in the LimeSurvey management interface will only be able to see users they create or users that belong to at least one same group. The default value can be overridden in the global settings dialog or edited in config.php.
  • filterxsshtml: This setting enables the filtering of suspicious html tags located within surveys, groups, and questions and answer texts in the administration interface. Leave this to 'false' only if you absolutely trust the users you created for the administration of LimeSurvey and if you want to allow these users to be able to use Javascript, Flash Movies, etc.. The super admins never have their HTML filtered. The default value can be overridden in the global settings dialog or edited in config.php.
  • demoMode: If this option is set to 'true' in config.php, then LimeSurvey will go into demo mode. The demo mode changes the following things:
    • Disables admin user's details and password changing;
    • Disables the upload of files on the template editor;
    • Disables sending email invitations and reminders;
    • Disables the creation of a database dump;
    • Disables the ability to modify the following global settings: site name, default language, default HTML editor mode, XSS filter.


  • sessionlifetime: Defines the time in seconds after which a survey session expires. It applies only if you are using database sessions. If you do use database sessions, change the parameter in config.php or override the default value from the global settings dialog.
  • memorylimit: This determines how much memory LimeSurvey can access. '128 MB' is the minimum (MB=Megabyte) recommended. If you receive time out errors or have problems generating statistics or exporting files, raise this limit to '256 MB' or higher. If your web server has set a higher limit in config.php, then this setting will be ignored.
Bitte beachten Sie, dass solche lokalen Einstellungen durch globalen Server-Einstellungen überschrieben werden können.

Zur Erhöhung der Speicherlimits auf 128M könnten Sie auch folgendes versuchen:

  • memory_limit = 128M in der PHP-Konfigration Ihres Servers (php.ini-Datei) setzen (empfohlen, wenn Sie Zugriff haben)
  • memory_limit = 128M in einer php.ini Datei im LimeSurvey Stammverzeichnis
  • php_value memory_limit 128M in einer .htaccess-Datei im LimeSurvey Stammverzeichnis
  • max_execution_time: Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. To be allowed to export big survey data and statistics, LimeSurvey try to set it by default to 1200 seconds. You can set a bigger time or a lower time if needed. Only accessible via php config file.


  • dropdownthreshold (Obsolete since 2.50): When "R" is selected for $dropdowns, the administrator is allowed to set a maximum number of options that will be displayed as radio buttons, before converting back to a dropdown list. If there is a question that has a large number of options, displaying all of them at once as radio buttons can look unwieldy, and can become counter-intuitive to users. Setting this to a maximum of, say 25 (which is the default) means that large lists are easier to be used by the administrators for the survey participant.
  • repeatheadings: With the Array question type, you'll often have a lot of subquestions, which - when displayed on screen - take up more than one page. This setting lets you decide how many subquestions should be displayed before repeating the header information for the question. A good setting for this is around 15. If you don't want the headings to repeat at all, set this to 0. This setting is overridden in the global settings dialog (New in 2.05 ).
  • minrepeatheadings: The minimum number of remaining subquestions that are required before repeating the headings in Array questions. The default value is 3 and it can be edited in config.php.
  • defaulttemplate: This setting specifies the default theme used for the 'public list' of surveys. This setting can be overridden in the global settings dialog or edited in config.php.
  • defaulthtmleditormode: Sets the default mode for the integrated HTML editor. This setting can be overridden in the global settings dialog or edited in config.php. The valid settings are:
    • 'inline' - Inline replacement of fields by an HTML editor. Slow but convenient and user friendly;
    • 'popup' - Adds an icon that runs the HTML editor in a popup if needed. Faster, but HTML code is displayed in the form;
    • 'none'- No HTML editor;
  • column_style: Defines how columns are rendered for survey answers when using display_columns. It can be edited in the config.php file. The valid settings are:
    • 'css' - it uses one of the various CSS methods to create columns (see the template style sheet for details);
    • 'ul' - the columns are rendered as multiple floated unordered lists (default);
    • 'table' - it uses conventional-tables-based layout;
    • NULL - it disables the use of columns.

Language & time

  • defaultlang: This should be set to the default language to be used in your administration scripts, and also the default setting for language in the public survey list. This setting can be overridden in the global settings dialog or edited in config.php.
  • timeadjust: If your web server is in a different time zone to the location where your surveys will be based, put the difference between your server and your home time zone here. For example, I live in Australia, but I use a US web server. The web server is 14 hours behind my local time zone. So my setting here is "14". In other words, it adds 14 hours to the web servers time. This setting is particularly important when surveys timestamp the responses. This setting can be overridden in the global settings dialog or edited in config.php.

Survey behavior

  • deletenonvalues: Use this feature with caution. By default (a value of 1), irrelevant questions are NULLed in the database. This ensures that the data in your database is internally consistent. However, there are rare cases where you might want to hold onto irrelevant values, in which case you can set the value to 0. For example, you ask a male person his gender, and he accidentally says 'female' and then answers some female-specific questions (questions that are conditioned on being female, so are only relevant for women). Then, he realizes his mistake, backs up, sets the gender to 'male', and continues with the survey.  Now, the female-specific questions are irrelevant. If $deletenonvalues==1, those irrelevant values will be cleared (NULLed) in the database. If $deletenonvalues==0, his erroneous answers will not be deleted, so they will still be present in the database when you analyze it.
  • shownoanswer: When a radio button/select type question that contains editable answers (i.e.: List, Array questions) is not mandatory and 'shownoanswer' is set to 1, an additional 'No answer' entry is shown - so that participants may choose to not answer the question. Some people prefer this not to be available. This setting can be overridden from the global settings dialog or edited in config.php. Valid values are:
    • '0': No;
    • '1': Yes;
    • '2': The Survey admin can choose.
  • printanswershonorsconditions: This setting determines if the printanswers feature will display entries from questions that were hidden by conditions-branching (Default: 1 = hide answers from questions hidden by conditions).
  • hide_groupdescr_allinone: This setting is relevant for all-in-one surveys using conditions . When this is set to 'true', the group name and description is hidden if all questions in the group are hidden. The default value is 'true' - hides group name and description when all questions in the group are hidden by conditions. It can be edited in config.php.
  • showpopups:  Show popup messages if mandatory or conditional questions have not been answered correctly:
    • '1'=Show popup message (default);
    • '0'=Show message on page instead;
    • '-1'=Do not show the message at all (in this case, users will still see the question-specific tips indicating which questions must be answered).

Development and debugging

  • debug: With this setting, you set the PHP error reporting to E_ALL. This means that every little notice, warning or error related to the script is shown. This setting should be only switched to '1' if you are trying to debug the application for any reason. If you are a developer, switch it to '2'. Don't switch it to '1' or '2' in production since it might cause path disclosure. The default value is '0' and it can be edited in config.php.
  • debugsql: Activate this setting if you want to display all SQL queries executed for the script on the bottom of each page. Very useful for the optimization of the the number of queries. In order to activate it, change the default value to '1' from the config.php file.

In the case in which you experience an error in the application, we strongly recommend to activate the debug setting in order to get a more detailed error that you can submit with the bug report:



All the settings from below can be overridden in the global settings dialog.

  • 'emailmethod: This determines how email messages are being sent. The following options are available:
    • 'mail:' it uses internal PHP mailer;
    • 'sendmail:' it uses sendmail mailer;
    • 'smtp:' it uses SMTP relaying. Use this setting when you are running LimeSurvey on a host that is not your mail server.
  • 'emailsmtphost: If you use 'smtp' as $emailmethod, then you have to put your SMTP-server here. If you are using Google mail you might have to add the port number like $emailsmtphost = ''.
  • emailsmtpuser: If your SMTP-server needs authentication then set this to your user name, otherwise it must be blank.
  • emailsmtppassword: If your SMTP-server needs authentication then set this to your password, otherwise it must be blank.
  • emailsmtpssl: Set this to 'ssl' or 'tls' to use SSL/TLS for SMTP connection.
  • maxemails: When sending invitations or reminders to survey participants, this setting is used to determine how many emails can be sent in one bunch. Different web servers have different email capacities and if your script takes too long to send a bunch of emails, the script could time out and cause errors. Most web servers can send 100 emails at a time within the default 30 second time limit for a PHP script. If you get script timeout errors when sending large numbers of emails, reduce the number in this setting. Clicking the 'send email invitation' button from the token control toolbar (not the button situated on the right of each token) sends the <maxemails> number of invitations, then it displays a list of the addresses of the recipients and a warning that there are more emails pending than could be sent in one batch. Continue sending emails by clicking below. There are ### emails still to be sent. and provides a "continue button" to proceed with the next batch. I.e., the user determines when to send the next batch after each batch gets emailed. It is not necessary to wait with this screen active. The admin could log out and come back at a later time to send the next batch of invites.

Statistics and response browsing

  • filterout_incomplete_answers: Control the default behavior of filtering incomplete answers when browsing or analyzing responses. For a discussion on incomplete responses see our browsing survey results wiki. Since these records can corrupt the statistics, an option is given to switch this filter on or off in several GUI forms. The parameter can be edited in the config.php. The following options are available:
    • 'show': Allows you to visualize both complete and incomplete answers;
    • 'filter': It shows only complete answers;
    • 'incomplete': Show only incomplete answers.
  • strip_query_from_referer_url: This setting determines if the referrer URL saves the parameter or not. The default value is 'false' (in this case, the referrer URL saves all parameters). Alternatively, this value can be set to 'true' and the parameter part of the referrer URL will be removed.
  • showaggregateddata: when activated, additional statistical values such as the arithmetic mean and standard deviation are shown. Furthermore, the data is aggregated to get a faster overview. For example, results of scale 1+2 and 4+5 are added to have a general ranking like "good" (1/2), "average" (3) and "bad" (4/5). This only affects question types "A" (5 point array) and "5" (5 point choice).
  • PDF Export Settings: This feature activates PDF export for printable surveys and Print Answers. The PDF export function is totally experimental and the output is far from being perfect. Unfortunately, no support can be given at the moment - if you want to help to fix it, please get in touch with us.
    • 'usepdfexport': Set '0' to disable and '1' to enable;
    • 'pdfdefaultfont': It represents the default font that will be used by the pdf export function. The default value is 'auto'. To change it, you have to set it to one of the PDF core fonts.
    • 'alternatepdffontfile': It's an array with language keys and their corresponding font. The default font for each language can be replaced in the config.php file;
    • 'pdffontsize': it shows the font size for normal texts; For the title of the survey, it is <pdffontsize>+4, while for the group title is <pdffontsize>+2. It can be edited in the config.php file or from the [Global settings|global settings]] dialog;
    • 'notsupportlanguages': it includes a list with the languages for which no PDF font was found. The list includes Amharic ('am'), Sinhala ('si'), and Thai ('th'), and it can be found in the config-defaults.php file;
    • 'pdforientation': Set 'L' for Landscape or 'P' for portrait format. It can be edited from the config.php file.
  • Graph setting
    • 'chartfontfile': Sets the font file name that is used to create the statistical charts. The file has to be located in the fonts directory, located in the LimeSurvey root folder. It can be edited in the config.php file;
    • 'alternatechartfontfile': It's an array with language keys and their corresponding font. It can be edited in the config.php file.
  • showsgqacode: This setting is used at the printable survey feature and defaults to 'false. If you set showsgqacode = 'true';, the IDs of each question - and answer if applicable - will be shown. These IDs match the column heading at the Lime_survey_12345 table, which holds the answer data for a certain survey. These IDs can be used for a code book for manual database queries.

LDAP Einstellungen (Englisch)

Dieses ausführliche Kapitel wurde verschoben, aber noch nicht übersetzt: LDAP Einstellungen.


Starting with LimeSurvey 2.05, authentication will be handled by plugins. As a result, the information below might be outdated. See the plugins wiki for most up to date information.

Delegieren der Anmeldung am Webserver

System-Admins wollen vielleicht ihre eigene Umfragenadministrations-Anmeldung mit einem zentralen Anmeldedienst (z.B. Active Directory, openLdap, Radius, ...), anstatt die interne DB nutzen. Ein einfacher Weg dazu ist dieses System. LimeSurvey wird der vom Webserver zurückgegebenen Authentifizierung vertrauen! Zur Aktivierung muss folgendes erledigt werden:

  • $useWebserverAuth in der config.php auf 'true' setzen
  • Die Anmeldung auf der Serverseite aktivieren

Bitte beachte:

  • LimeSurvey wird dann seinen eigenen Login-Prozess umgehen (durch Nutzung eines Loginnamens ohne Abfrage eines Passwortes)
  • Das kann nur das LimeSurvey-Administrations-Loginsystem ersetzen, nicht das Umfragen-Einladungssystem (Benutzerschnittstelle)

Delegieren der Anmeldung ohne Import der Benutzer

Bitte beachte, dass </u> standardmäßig eine Delegierung der Anmeldung nicht das Authentifizierungssystem von LimeSurvey außer Kraft setzt===: Dies bedeutet, dass LimeSurvey dann zwar keine Passwörter verwaltet, trotzdem aber in der DB die User mit den entsprechenden Berechtigungen eingetragen werden müssen, um Zugriff auf die Umfragenresourcen zu erhalten.

Ein User hat nur Zugriff, wenn:

  • Er vom Webserver authentifiziert wurde
  • Sein Loginname in der LimeSurvey DB steht (der User hat die Berechtigungen, wie in der DB angegeben).

Delegieren der Anmeldung mit Import der Benutzer

Wenn eine große DB verwaltet wird, ist es manchmal einfacher neue User, welche z.B. schon in einer Benutzer-Tabelle von dir stehen, automatisch in die LimeSurvey DB zu importieren.

  • $WebserverAuth_autocreateUser: Wenn 'true' wird LimeSurvey versuchen, User, welche vom Server authentifiziert wurden und noch nicht in der LimeSurvey DB sind, automatisch zu importieren
  • $WebserverAuth_autouserprofile: Ein Array, welches das Standard-Profil eines Users beschreibt, der so importiert wird (beinhaltet Nick-, Vor- und Nachname, E-Mail-Adresse und Berechtigungen)

Wenn das standardmäßige Profil an die User angepasst werden soll, muss eine einfache Funktion geschrieben werden: hook_get_autouserprofile: Hole mit dieser Funktion die benötigten Benutzerdaten (beinhaltet Vor- und Nachname sowie die E-Mail-Adresse) aus einer Datenbank, oder z.B. aus einem LDAP Verzeichnis. Es kann auch seine Berechtigungen basierend auf z.B. externen Gruppen geändert werden.

Die hook_get_autouserprofile Funktion nimmt nur den Loginnamen als Argument und kann folgendes zurückgeben:

  • 'False' oder ein leeres Array: In diesem Fall wird dem User der Zugriff auf LimeSurvey verweigert
  • Ein Array mit allen Benutzerdaten, wie in $WebserverAuth_autouserprofile beschreiben
function hook_get_auth_webserver_profile($user_name)
     // Retrieve user's data from your database backend (for instance LDAP) here
     ... get $user_name_from_backend
     ... get $user_email_from_backend
     ... get $user_lang_from_backend
     ... from groups defined in your backend set $user_admin_status_frombackend_0_or_1
     return Array(
                     'full_name' => "$user_name_from_backend",
                     'email' => "$user_email_from_backend",
                     'lang' => '$user_lang_from_backend',
                     'htmleditormode' => 'inline',
                     'templatelist' => 'default,basic,MyOrgTemplate',
                     'create_survey' => 1,
                     'create_user' => 0,
                     'delete_user' => 0,
                     'superadmin' => $user_admin_status_frombackend_0_or_1,
                     'configurator' =>0,
                     'manage_template' => 0,
                     'manage_label' => 0);

     // If user should be denied access, return an empty array

     // return Array();
The optionnal 'hook_get_auth_webserver_profile' function is for advanced user usage only! For further details, please read the comments from the config-defaults.php file.

Umschreibung des Benutzernamens

In einigen Fällen haben User einen anderen externen Namen als den LimeSurvey Usernamen, vielleicht ist deshalb das folgende Feature des Umschreibens der Namen sinnvoll. Dies wird in LimeSurvey durch den $userArrayMap Parameter erledigt. Z.B. gibt es keinen 'admin' Usernamen in einer externen DB. Um trotzdem als 'admin' eingeloggt zu werden muss der externe Benutzername, nennen wir ihn 'myname', umgeschrieben werden. Das sieht dann so aus:

'auth_webserver_user_map' => array ('myname' => 'admin');

Nach einer erfolgreichen Anmeldung mit dem 'myname' Loginnamen und des Passwortes wird man direkt als LimeSurvey 'Admin' Benutzer akzeptiert.

Diese Option ist sicherheitsrelevant, deshalb nur sorgsam benutzen und die config.php vor Schreibzugriff vom Webserver schützen!


A user can open the LimeSurvey login page at and type the username and the one-time password which was previously written into the users table (column one_time_pw) by an external application.

Diese Einstellung muss aktiviert werden (use_one_time_passwords => true) um die Verwendung von Einmal-Passwörtern zu ermöglichen (Standard = false). Mehr Informationen finden Sie auf der Seite Benutzer verwalten.

Erweiterte Ordner Einstellungen

  • homeurl: This should be set to the URL location of your administration scripts. These are located in the /limesurvey/admin folder. This should be set to the WEB URL location - for example, Don't add a trailing slash to this entry. The default setting in config.php attempts to detect the name of your server automatically using a php variable setting - {$_SERVER['SERVER_NAME']}. In most cases, you can leave this and just modify the remainder of this string to match the directory name you have put the LimeSurvey scripts in.
  • publicurl: This should be set to the URL location of your 'public scripts'. The public scripts are those located in the "limesurvey" folder (or whatever name you gave to the directory that all the other scripts and directories are kept in). This settings is available in config.php and it is used when token emails are sent.
  • tempurl: This should be set to the URL location of your "/limesurvey/tmp" directory - or to a directory in which you would like LimeSurvey to use to store temporary files, including uploads. This directory must be set to read & write for your webserver (e.g. chmod 755).
  • imagefiles: By default, you should leave this pointing to the URL location of /limesurvey/admin/images - where the images are initially installed. You may, however, prefer to move these images to another location/ If this is the case, point this to the URL directory where they are stored.
  • homedir: This should be set to the physical disk location of your administration scripts - for example "/home/usr/htdocs/limesurvey/admin". Don't add a trailing slash to this entry. The default setting in config.php attempts to detect the default root path of all your documents using the php variable setting {$_SERVER['DOCUMENT_ROOT']}. In most cases you can leave this and just modify the remainder of this string to match the directory name you have put the LimeSurvey scripts in.
  • publicdir: This should be set to the physical disk location of your 'public scripts'.
  • tempdir: This should be set to the physical disk location of your /limesurvey/tmp directory so that the script can read and write files.
  • sCKEditorURL: url of the fckeditor script.
  • fckeditexpandtoolbar: defines if the fckeditor toolbar should be opened by default.
  • pdfexportdir: This is the directory with the tcpdf.php extensiontcpdf.php.
  • pdffonts: This is the directory for the TCPDF fonts.
