Admin themes
Before updating the compatibility version number of your config.xml file, please be aware that enabling an incompatible admin theme can break the admin interface of the application.
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.
