Forum Database error 1064
 

Everyone once in a while I get a VBulletin Database Error in my mailbox:

Database error in vBulletin 4.2.0:

Invalid SQL:
UPDATE user SET rmEmailDate = UNIX_TIMESTAMP() rmEmailCount = 1 WHERE TIMESTAMPDIFF(DAY, FROM_UNIXTIME(lastactivity), FROM_UNIXTIME(UNIX_TIMESTAMP())) >= 60 AND usergroupid IN ('10','11','2') AND rmEmailCount = 0 AND options & 16 AND rmoptout = 0 LIMIT 10;;

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 'rmEmailCount = 1 WHERE TIMESTAMPDIFF(DAY, FROM_UNIXTIME(lastactivity), FROM_UNIX' at line 1
Error Number : 1064

Any idea what this can be?

Thanks,
Dirk
