(User CP) Database Error vBulletin 3.0.6: Invalid SQL

I am an admin/member of another board which also has the "User CP" option like the one on this board. I have been getting the following error when clicking on the User CP link at the top of my board:

Database error in vBulletin 3.0.6:

AND subscribethread.userid = 2
AND thread.visible = 1
AND lastpost > 1197542220
AND deletionlog.primaryid IS NULL

I apologize in advance if I have hit the wrong forum with this, but if anyone could shed some light on a fix to this, it would be greatly appreciated.

Thank you.
