[Plugin: WP phpBB Bridge] Logged out when accessing WP admin

This plugin worked perfectly up until we switched from standard http to https. Now when we log in, that’s fine, but if you try and go to site.com/wp-admin/ it brings you to the logged out page. I’ve tried everything I can think of but I can’t figure out where to start debugging. I’ve noticed in the forums I’m not the only person to have this problem. I don’t have to remove the plugin, I just need to turn off the bridge (through mysql). phpBB works fine in full SSL mode and so does WP. I’m open to suggestions. the site is http://www.sfcfleet.com and yes, phpBB is in a subfolder of WP.

/var/www <- WordPress
/var/www/forums <- phpBB

Again it did work perfectly fine before switching everything over to https.
