Two days ago I added a some new features to the Chatbox, but unfortunately caused a bug which was causing the log-in information not to be retained, causing people to be logged out. However, just moments ago I removed the buggy code and believe that the problem has been fixed.
If you could let your members know to clear their cache and cookies, then try logging in again and browsing the forum normally, it should work for them.
Please do let me know if there are any further problems with the functionality of the board.
I apologize for any inconvenience this may have caused.
