Database Error on Registration
 

So, I have my board set to log database errors, and I came across this one, and I'm not sure what happened. Can anyone explain it to me? It seemed to be a big deal, because the error occurred during an attempted registration, and I just want to make sure people are still able to register...

Here is the error message:

Code:
Database error in vBulletin 3.8.2:

Invalid SQL:

SELECT COUNT(userchangelog.changeid) AS change_count
FROM userchangelog AS userchangelog
LEFT JOIN user AS user ON(user.userid = userchangelog.userid)
LEFT JOIN user AS adminuser ON(adminuser.userid = userchangelog.adminid)
WHERE userchangelog.fieldname = 'username' AND change_time >= 1210734591 AND (userchangelog.oldvalue = 'cendDeldral' OR userchangelog.newvalue = 'cendDeldral');

Is something wrong that could be preventing people from registering? This is the first time I've seen this error...
