BuddyPress.org

The reason why it’s not working is because you’re not using the method included in the plugin.

The groups posting ability relies on XMLRPC, which cannot be re-included when bbPress is loaded via the BuddyPress installation. Using my included method of deep integration will still allow for this functionality to work.

Science!

When you go to create a group forum, WordPress is loaded, BuddyPress is loaded, bbPress gets loaded through XMLRPC, which without my deep integration method will try to reload WordPress again, over-writing or clearing all of the bbPress functions/variables/hooks/filters, killing the XMLRPC ability to transmit data through the pipe.

Just bumped to 1.0.3. The plugin now does enhanced checking for the visibility of the BuddyBar/AdminBar as it would previously fail if the bar was hidden in bp-custom.php or wp-config.php.

If you are receiving errors regarding BP_Roles in your BuddyBar, apply patch #1032 to your WPMU trunk installation.
