I’m using buddy press with a memberpress integration and a memberoni child theme in wordpress 5.8 and the latest version of buddy press. local menu bars have suddenly disappeared from my group page and profile page. for example, on the group page I used to see Home/Forum/members/Invite/Email options/Manage. This whole menu is now missing. On the profile page, the menu bar listing profile/notifications/messages/etc/etc/etc is also missing. I compared the live site against our staging site and those menus are still present in the staging site. Buddy Press settings are the same in both environments, except there are some weird phantom checkmarks in the dev environment. I have checked every setting I can think of and have no idea where these menus have gone or where I should look. Am not a developer. Help? live site settings dev site settings
The devsite settings are indeed strange.
I doubt anyone can diagnose the issue based on the info provided.
You could try some standard debugging.
You could try deactivating memberpress and / or switching momentarily to a WP theme like 202 and see if the issues persist – that will give you more info re possible causes.
