Also I lost control of bbPress dashboard. It doesn’t appear anymore with the profile page link. When I try to access it by typing /bb-admin/ then it will redirect me to the forum’s main page.
One more thing. When I login using bbPress, it reflects on WP meta widget but when I try to access WP dashboard it asks for login information. That means I am not logged in. I think the WP is not checking the cookie correctly or bbPress is not setting cookie the right way.
Meanwhile I will try a WP plugin to let it communicate with bbPress instead of using a bbPress plugin as above.
