I have the same problem, I just haven’t used BuddyPress. Fresh WP 3.0.1 multisite and bbPress installed from svn trunk (as suggested by friend). I’ve integrated bbPress with WP and since then I can’t go to /bb-admin/ (being redirected to the root of the forum) nor I can reply on default topic (created by installer). I’ve checked with other users and everyone can log in but noone can reply or create new topic.
I’ve checked the database and wp_roles_map in bbPress db is:
array (
‘administrator’ => ‘keymaster’,
‘editor’ => ‘moderator’,
‘author’ => ‘member’,
‘contributor’ => ‘member’,
‘subscriber’ => ‘member’,
)
In WP database (table wp_usermeta) wp_capabilities for my user:
array (
‘administrator’ => ‘1’,
)
There is also wp_2_capabilities field which contains same serialized array.
