I am getting this error on the CMPS:

Database error in vBulletin 3.5.4:

Invalid SQL:
SELECT dateline, userid FROM customavatar WHERE userid =;

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 1
Error Number : 1064

I see the error from a few people, I ran the task a few times and still get the same result.

Thank you in advanced
