BuddyPress.org

Thanks for responding. Yes, the WP install is in the Streaming directory, and “Anyone Can Register” is enabled. It actually worked for awhile; this is a new development.

The “Register with Facebook” button works great, thankfully.

No. THat has no effect. I’ve disabled EVERYTHING except BuddyPress, and it has no effect.

We solved it. It was a caching issue. Really threw a wrench in the works.

I think it was wp-super-cache in my case. It was installed in the wordpress folder on the server (not the plugins folder). When I removed it, it worked.
