Not sure if this is what you mean, but go into ACP - > Forums & Moderators -> Forum Manager -> Then set "Forum is Active (Will not appear if set to no, but remains accessible if the forum's URL is known)" to No.
ACP - > Forums & Moderators -> Forum Manager -> Display Order , set to 0 and save.
If, to if if she hides the sub forum in it paginates it main but when neither entering in the category you leave.. something has to have not well on in the depth of the sub forums
