However... when I enable this hack it shows me following:

Database error in vBulletin 3.8.1:

Invalid SQL:
SELECT groupid, name, visible, discussions, picturecount, members, lastpost, lastupdate, 
dateline AS createtime FROM socialgroup WHERE groupid IN ();

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 ')' at line 2
Error Number  : 1064

It is not the edit, as I haver undone it with the editor... but the failure still showed up. I can only browse index.php when the mod is disabled... I guess this is not what you wanted...
