Role maps were working fine. But then I installed User Role Editor by Vladimir Garagulya and when it failed to produce the results I wanted, I hit reset, deactivated it, and uninstalled/deleted it.
WordPress users are "Members" and bbPress users are "Inactive (no role)".
I can't change them as one anymore.
I use: bbPress 1.0.3, WordPress 3.1.1, and Buddypress.
bbPress and WordPress were fully integrated and working together before this issue.
I posted on the bbPress Forums, but I thought it couldn't hurt to post here.
