Coppermine1.1.4, phpBB 2.0.19... can't log in

[Soliloquy]

Once I enable bridging, Coppermine says I am no longer logged in.  I log onto phpBB and get bounced back to Coppermine, where it still says I'm not logged in.  I've disabled bridging and gone through the bridging manager many times but can't figure out what I'm doing wrong.  Help me, Obi Wan Kenobi!

In phpBB's control panel or coppermine's?  I can now no longer access the admin panel, bridge manager, or configuration in standalone coppermine, and my testuser account can't log in at all.
