Maybe this is a common issue but I can find a solution yet. I’ve installed the Forum plugin. Created a forum and topic in the admin. However I get an error when I try to view it:

Fatal error: Call to undefined function bb_get_id_from_slug() in blahblah/wp-content/plugins/buddypress/bp-forums/bp-forums-functions.php on line 137
Also, in the “Forums for Groups” section of the admin, when I select “Use existing installation” it asks for the location of the bb-config. A part of me feels it should automatically know the location however it doesn’t and neither do I. I’m unable install the forum for groups as such.

Any advice on the fatal error or if any of this is related?
