Need to customize 404 restrictive page
To whom it may concern: wpForo works properly, and displays 404 when I have the permissions applied to restrict "visibility/view" of detailed topics.
I am using Ultimate Member and wpFusion as well. What I need is:
1) A way to customize the 404 message that is displayed
2) add shortcodes to the 404 display so I can place appropriate messages for "guests not logged in" versus "inactive members that need to renew"
