I had this problem here and i change my query to:
SELECT f.*, c.id as cat_id, c.position as cat_position, c.state as
cat_state, c.name as cat_name, c.description as cat_desc,
c.image, c.url, m.member_name as mod_name, m.member_id as
mod_id, m.is_group, m.group_id, m.group_name, m.mid
FROM ibf_forums f
INNER JOIN ibf_categories c on f.id_cat=c.id_cat
LEFT JOIN ibf_moderators m ON (f.id=m.forum_id)
WHERE c.id=f.category
ORDER BY c.position, f.posit
It works fine to me.
