Me too.
God I’ve spent a weekend trying to sort our a decent forum:
bbpress would not integrate with my WP database. After a day of trying I gave up!
bbphp just did look right gave that an hour.
buddypress looks functionally good but I tried before to integrate with my Magazine Premium theme but there were too many problems .
Buddypress themes seem few and far between. Most don’t support menus (in their menu bars: not their widgets!).
The ones that do offer compatibility dont run on my site: Detox for the same reason as you and Easybuddy give another PHP error.
Havnt tried it …yet (only soooo many hours in the day!) but I’ve come across Michael Kuhlmans blog http://www.michaelkuhlmann.com/blog/2010/07/08/how-to-add-custom-menus/
who walks you though adding custom menus to the main menus of a buddypress theme.Not saying that’s what you are looking for but may be a good way of pimping a basic theme??
