You need to ensure you’re changing the cookie keys located in the bb_config and wp_config files. Also make sure you’re using the appropriate wp/bbp integration plugin.
this video helps greatly.

(you can skip some of the beginning, it’s him installing wordpress.)
Not sure I’m changing both the cookie keys, but I am making sure they match. BTW…I’m using WPMU. Latest versions of both products.
I started over from scratch. I’m still having the problem. I log into one, but the other remains logged out. Both bbpress and WPMU recognize my User information, but I have to log in or log out twice.
i enabled this plugin in MU blog(2.8.6) and bbpress 1.0.2
but i get this ERROR
