When I change a group name here…

Admin > Edit details > Group name

… and press ”Save Changes”, I get this error …

Fatal error: Call to undefined function bb_update_forum() in /home/XXX/public_html/wp-content/plugins/buddypress/bp-forums.php on line 147

XXX = account name

I’ve never see this before. Any recommendations for diagnosis?

I was able to replicate this issue. However, when I changed visibility from Hidden to Public, the error no longer appeared. So, fine now. I’ll report if I see it again.

Found the problem. I’ll post the solution; perhaps it will be helpful for others.

I’d deactivated plugins in order to setup a subdirectory network (for use with Group Blogs). In doing so, the bbPress installation became “disconnected.” I went to Network Admin, set up bbPress from an existing install (the bb-config.php file was extant), and voila, reconnected.

Resolved, with gratitude, due to the collective knowledge of a number of BP people who’d posted about related issues. Thanks!
