Thread:Extension talk:MediaWikiChat/Fatal Error

Hi all. I'm having some trouble effectively implementing the extension. First, my versioning,

MediaWiki	1.23.1 PHP	       5.5.14 (apache2handler) MySQL	       5.6.19

When I enable the extension in LocalSettings the chat feature itself works but it breaks the rest of the site. Any other page I navigate (including Main) gives:

Fatal error: Class 'wAvatar' not found in ...\extensions\MediaWikiChat\MediaWikiChatClass.php on line 37

Anyone have any suggestions?
