Because of this I cannot run WP phpBB Bridge plugin - users cannot ingle logon due to cookies.
But could you introduce a setup, where single logon is not there and only the register link is forwarded to the phpBB register page and where the user database of WordPress is synced with the phpBB users database?
Should work and every WP phpBB Bridge feature should be there exept the singlo logon feature. With my project a synced user database would be very handy.
Thank you and Cheers,
