Theme location
From MoodleDocs
In the standard Moodle distribution, all themes are placed in the theme/ directory of moodle. However, it is possible to use a different location for themes with version 1.7.
Changing theme Location
Starting from Moodle 1.7, the location of themes may be altered, using the variables $CFG->themewww and $CFG->themedir
If you wish to place themes in a subdirectory called 'my_moodle_themes', your config.php might look like this:
$CFG->wwwroot = 'http://my.moodle.site.edu'; $CFG->dirroot = '/var/www/my.moodle.site.edu/public_html'; $CFG->themewww = $CFG->wwwroot . '/my_moodle_themes'; $CFG->themedir = $CFG->dirroot . '/my_moodle_themes';
