Survey themes
To fix an incompatible survey theme, add the "compatibility" option with the correct version number inside the "config.xml" file for this theme.
This can be done in 2 ways:
- Export the survey theme and access the config.xml file.
- If you have access to the server, the config.xml is located inside "upload/themes/survey/YOURTHEMENAME" of the applications root directory.
Carefully examine in a dummy survey which changes you need to make before using your custom survey theme in a live environment.
Admin themes

If this happens to you, make sure to manually set the theme inside the database table "settings_global" to the default theme "Sea_Green". You can always check in the "application/config/config-defaults.php" file what name should be used in the database $config['admintheme'] = 'Sea_Green';.
To enable an admin theme again, add the "compatibility" option with the correct version number inside the "config.xml" file for this theme.
Question themes
To make them compatible with a new version of LimeSurvey the compatibility tag in config.xml has to be updated, located in "NAME/survey/questions/answer/QUESTIONTYPENAME/config.xml" within the structure of the question theme.
