@tskpbls seems working fine to me https://prnt.sc/sklvtvm, I was able to access as super admin and group admin for a hidden group with forum enabled on that specific group.
Ok, let’s investigate further then …
I reinstalled default 2020 WP theme, deactivated all plugins (double checked) but bbpress and buddypress, although I’ve kept wpmu admin dashboard plugin… I am on a very fresh install (less than 24 hours)
I am still facing the same issue :
Link to a google drive folder with screenshots (public / private / hidden) : https://drive.google.com/drive/folders/1MWlx_eMelveGBSK_9MHEIoLd1NJRHz1D?usp=sharing
buddypress is installed according to this codex guideline : B. Network-wide Activation – BuddyPress root blog in Secondary Site
Buddypress seems to work ok, activity, group and email tabs under admin menu of the admin network page, main site shows forum tabs only and subsite 1 (?id=2) holds buddypress frontend pages.
Soooo, maybe a clue here : Why does the group edit screen say “aucun forum” (no forum) attached to group when in the meantime I can see the forum tab and the input text boxes of the first subject when group is not hidden?
Many infos here, sorry for that, but I guess I can’t be more accurate than that in my perception of the problem.
Hope this helps you to understand the problem better.
@tskpbls, yes I am able to replicate the issue now.
When bbPress is active, the hidden group is not visible on my-groups tabs.
bbPress not active: https://prnt.sc/skoogl
bbPress active: https://prnt.sc/skoovq
Group counting still including hidden groups, but not visible in my group’s listing.
You can report it here
