Any idea why i'm getting a databaser error?

Invalid SQL:

        SELECT
            user.username, user.usergroupid, user.lastvisit, user.usertitle,
            session.userid, session.inforum, session.lastactivity,
            IF(displaygroupid=0, user.usergroupid, displaygroupid) AS displaygroupid, infractiongroupid
             , user.bop5_userfont AS bop5_userfont 
        FROM vB_session AS session
        LEFT JOIN vB_user AS user ON(user.userid = session.userid)
        WHERE session.lastactivity > 1408204549 AND user.usergroupid IN (13,14,5,7,6,-1)
        ORDER BY username ASC;

MySQL Error   : Unknown column 'user.bop5_userfont' in 'field list'
