There are two parameters that are set in the config.php file:

To change the priority of page themes, modify the parameter to reflect the new order. The default is set to ('page', 'course', 'category', 'session', 'user', and 'site').
The remaining values, which are listed next, are set within the config.php file of a particular theme.
