Disabling ComfortUpdate

To disable ComfortUpdate to avoid receving New release available popup messages after each new release, you can add the following option to your "config.php" file (which is located in /limesurvey/application/config):

'updatable' => false

However, we strongly recommend not disabling this, as you might miss important security updates.

Troubleshooting

I get some error during ComfortUpdate

As a first step, please try to run the same step again after one minute. Occasionally, the server has to first generate the update package, which might take a minute. If it still does not work, check the other solutions in this troubleshooting section.

The ComfortUpdate server is not responding - cannot connect to ComfortUpdate Server

Starting December 2022 the connection default to our updated server was changed to only use SSL. This requires that the OpenSSL PHP library on your server is properly configured and activated and that your server is allowed to connect by HTTP SSL connection to the outside (to our server comfortupdate.limesurvey.org). If one of these requirements is not met, you will get this message. A temporary workaround (which we don't recommend) is to disable this requirement in the /application/config/updater_version.php by setting

$config['comfort_update_server_ssl'] = 0;

Blank page on step 3

If you get a blank page on step 3, it usually means that the memory limit of your PHP configuration is set too low. During that step, LimeSurvey tries to create a database backup and a file backup (of the files that will be replaced).

Using a proxy server to connect to update.limesurvey.com

If you are behind a proxy, you may have to adjust some settings to be able to use ComfortUpdate. In LimeSurvey 2.05 (later than build 140404), you can set the details of your proxy server in the configuration file (see the general settings wiki).

For earlier versions, you have to edit the http.php file in your LimeSurvey installation. Have a look at the variables in the first lines of this file in a text editor and add values if needed.

Example: Connect to a proxy server 111.111.111.111 port 1234 without authentication and edit the following lines to look like:

  // This code is only for versions earlier than 2.05
  var $proxy_host_name="111.111.111.111";
  var $proxy_host_port=1234;

Depending on your version, you will find the file either in /admin/classes/ or in /application/libraries/admin/http/. There are pre-coded variables within the file. Therefore, only details of your proxy are needed. If your installation is running unusually slow, wrong proxy settings may be the cause.
