CometChat installed fine but not working.

A new version of this add-on was just released that hopefully will address this problem. While we've given the code a review and done some testing, please keep in mind that we've transitioned support over to the developer of the add-on, and expect their team to address support issues.

We've asked the developer to add any relevant notes and documentation relating to the new 2.0.3 release, so stay tuned.
Since it sounds like you purchased the add-on from somewhere else, I guess you'll need to contact CometChat themselves-- or whomever you purchased it from-- to obtain the new source code.
You might want to send a private message to the developer through our site if you're stumped.
