I checked from different computers, different browsers, different countries. It happens only when logged in.
It's possible that there is something wrong with my account I suppose.
I get the following:
HTML Code:
Warning: mysql_query() [function.mysql-query]: Unable to save result set in [path]/includes/class_core.php on line 408
Database error
The Graal Forums database has encountered a problem.
Edit: Maybe it happens if you have your account to view more posts than "Last Day" by default?
