Re: WP 2.7.1 with BBpress 1.0 rc1 integration problem
Sounds like you need to sync up all of your salts and keys, and check out the cookies that get dropped from both sides when logging in.
Remember you will still need the bbPress Integration plugin on the WordPress side to drop the bbPress cookies.
The way I do this, is to use Firefox, login through WordPress, and look at the cookies. Then delete them. Login through bbPress, look at the cookies. Which ones are missing from either side? Which information doesn’t match? That will be your clue to getting them synced up.
Once you know what you’re looking at, this process shouldn’t take more than 20 minutes.
