Re: Login Username & password issue?
bbpress-integration.php should add a “bbPress” tab in your WordPress admin under the Plugins tab.
Go to the bbPress tab. Did you fill in your bbPress table prefix?
The way this all should work is:
A new user registers on bbPress. The first time that new user browses to WordPress, he or she is added to the member list (prior to then, that new user is listed under “No Role for this Blog”).
The same should hold if you swap “bbPress” and “WordPress” in the above paragraph.
What are your $bb->wp_home and $bb->wp_siteurl settings in bbPress’ config.php?
