Re: Facebook connect
I was successful in the installation of Facebook plugin, BP-FBConnect with Buddypress installation at http://www.mekudos.com
The following was required for my installation:
1) WordPress MU version 2.7.1
2) Buddypress Trunk 1281 (does not work with RC-1)
3) BP-fbconnect.zip Plugin and activate Facebook Developer API key.
1) WordPress MU version 2.7.1: https://trac.mu.wordpress.org/browser/branches/2.7
2) Buddypress Trunk 1281: https://svn.buddypress.org/trunk/
3) BP-FBConnect Plugin: http://testbp.org/plugins/bp-fbconnect.zip
Hope this helps for those looking for Facebook Integration.
