I am getting the following error repeatedly mailed to me:

Database error in vBulletin 3.7.4:

Invalid SQL:
DELETE FROM vb_gwowroster_rosterinfo WHERE NOT (
locale IN('EU') AND
realm IN('Ravencrest') AND
charname 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 4
Error Number : 1064

Any help with this would be appreciated.
