MyBB Community Forums

Hello,
I have one category http://www.taahod.com/forumdisplay.php?fid=31
I can see threads and also sub forums likes but I can not find it in admin panel and index page?
Also I can check it in admin panel module=forum-management&fid=31 but not listed on forum list.
Cache cleaning won't help me.
Permissions checked.
How can I fix this problem?

Nice forum, I like the masturbation section the most

As for this thread, the "forum" that is missing, did it come with the site you merged or did it disappear after you merged and had it before the merge?
