Re: Cookie sharing – bbPress 1.0.1 & WPMU 2.7.1
What part isn’t working? Just not at all, you can’t log in with the same ID on both, or is it the logging in on one logs you out on the other? There are a few similarish errors, but they’re debugged differently.
As always, re-copy/paste the KEYs and SALTs from WPMU to BB, flush your cache and cookies, and try again. Even if you’re sure they’re right, it doesn’t hurt
define( 'WP_AUTH_COOKIE_VERSION', 1 ); should be in your bb-config, not wp-config.
