== I have changed the default theme and nothing works anymore. How can I switch back? ==
Use phpmyadmin / your mysql shell to execute the following query to change the default theme back to the matrix theme:
 UPDATE g2_PluginParameterMap SET g_parameterValue = 'matrix'
 WHERE g_pluginType = 'module' AND g_pluginId = 'core' AND g_parameterName = 'default.theme';

Afterwards, delete the db cache by browsing to <nowiki>http://example.com/gallery2/lib/support/</nowiki>, enter your password, click there on cache management and delete the db and template cache. Of course you need to replace example.com/gallery2/ with the actual address of your Gallery.
