BuddyPress.org

Excellent idea, unfortunately, I can’t make it work.
Using WPMU 2.9.2, BP 1.2.3 and malleable for BP 0.0.7 Hybrid child theme.

Menu expands but nothing is shown, all black in my case.
In default BP theme, works OK but is shown not on top of the page but just below the tabs.

Where should I start troubleshooting ? Regards,
