I’m having the exact same issue. Cache/cookies have been cleared, tried multiple browsers, etc. I have integrated WP with bbPress and all the user roles appear to be set up correctly (though I can’t imagine what else the problem could be…). Users are shared between WP and bbPress correctly, etc. but when I try to go to /bb-admin I’m simply redirected back to forums main, same as jbrzr3.
Out of ideas. WP + bbPress is an ideal solution for the site I’m working on but this is a pretty major roadblock.
