Hola Patriarka... muchas gracias por la sugerencia... pero me sigue dando el mismo error...

Código:

mySQL query error: SELECT *, me.avatar_location, m.view_avs, me.avatar_size, m.id as member_id, m.name AS  member_name, m.mgroup, f.name AS forum_name
                                                FROM ibf_posts p

                                                 LEFT JOIN ibf_topics t on (t.tid=p.topic_id and t.approved=1 and t.moved_to IS NULL)
