OK, fixed with the “put $bb->usercookie = ‘wordpressuser_[Insert MD5Hash]’; into the bb-config.php file” hack.
bbP 0.9.4 & WP (ahem) 2.0.11.
Unfortunately in a position that I can’t upgrade WP at the moment.
bbP is using the WP users table fine, but doubling up on the cookies for some reason.
For some reason, I’m getting two sets of cookies being set.
Both WordPress and bbPress are setting wordpresspass_ & wordpressuser_ cookies. The domains and paths are identical but the hash part of the key is the different.
Any ideas why WP and bbP might still be out of sync after following the instructions above?
