I don’t now, how to exclude menu only from that page. Thanks.

Have you tried setting up a custom menu that doesn’t include this page?

My theme support only one menu. Forum is working on page now and if page replace with category, forum will be working? Hope you stand me, I’m just newbie in WordPress.

How does that affect setting up a custom menu?

Can’t use 2 menu in one time. Forum is working on the page and it’s not include in menu categorie. I can create custom category in working menu. Is it some diffrent way? Maybe I dont know something.
