yes Sam i’ve always the www in front.
i’ve modified COOKIE_DOMAIN in wp-config with define(‘COOKIE_DOMAIN’, ‘.site.com’); (without www but with .)
and in bb-config $bb->cookiedomain = ‘.site.com’;
I can login in bbpress and in WP when i try to login i’m redirected to the same page (wp-login)… so with this nothing change.
What else can I try?
