Right I’ve narrowed this down.

I’ve redirected bbPress’ login to WordPress. That’s fine. Now here’s exactly what happens when you register.

1) Go to wp-register.php, fill in fields

2) Check email, get password

3) Login at wp-login.php

4) Go to forum, already logged in – INACTIVE

5) Log out of forum, log back in – ACTIVE

Obviously the last two steps are problems. Is this a cookie issue?
