How can I 'fix' bbPress in WP Multi Site

I am running WP 3.5.2 Multisite with BuddyPress 1.8, bbPress 2.3.2 and Brajesh Singh’s BP Multi Network 1.0 plugin from GitHub. I have everything working properly (I think) except group forums do not work :slight_frown:

At one point in the docs it points to a guys page who says you have to modify the bb-config.php but bbPress doesn’t use that any more as I understand it.

Any ideas? When trying to create a group, when you get to the forum page, it is blank. If you turn on debugging, you get:

Fatal Error: Using $this when not in object context in plugins/bbpress/includes/extend/buddypress/group.php, line 461

Anyone have any ideas?

Thanks in advance!
