This is the error I got on every version of this modification. The error happen only when I enabled this.

 Invalid SQL:
SELECT * from `thread`
                               Where  forumid  IN(2)
                               AND `postuserid` NOT IN ()
                               AND `dateline` <= '1323405149';

MySQL Error   : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')
                               AND `dateline` <= '1323405149'' at line 3

Disabling this resolved the issue.
