database error help

I hope this is the right section, but here it goes.

I have been getting a few database errors for quite some time now, and I'm thinking it may be a hack that i've installed but i've been unable to work out which one or if it is even one.

This is the error

Code:

Database error in vBulletin 3.6.4:

                                SELECT usergroupid FROM vb3_icon AS icon
                                INNER JOIN vb3_imagecategorypermission USING (imagecategoryid)
                                WHERE icon.iconid = 10
                                        AND usergroupid IN ();

hopefully the above will be able to help you track down the error and possible give me a fix to end this database error thats been going on for a while. (I've never had the error, so it makes it hard for me to know what is causing it)

Thanks.

Looks to be a mod that deals with assigining permissions .. possibly to the default post icons?
