Whenever I try to edit the main page of sryth.wikia.com, my browser (Firefox 15) gives me this message:

Unexpected non-MediaWiki exception encountered, of type "ReflectionException" exception 'ReflectionException' with message 'Class RTEUserPropertiesHandler does not exist' in /usr/wikia/slot1/code/includes/wikia/nirvana/WikiaSuperFactory.class.php:108 Stack trace:

I've been editing in another wiki, musicbee.wikia.com, and it's fine there.
