How To Restore Disappeared Members Tab
My logged-in Members used to see a "Members" tab located between the "Forums" and "Recent Posts" tabs as this support forum shows above, however that tab is now missing. How can I restore that "Members" tab for logged-in Members (not guests) to see?
That tab is a menu item. Firs you should make sure it exists in the wpForo Navigation menu: https://wpforo.com/docs/root/getting-started/forum-menu/
Then go to Dashboard > Forums > Usergroups admin page, edit the Registered Usergroup and check (enable) the "Front - Can view members" permission.
