BuddyPress.org

To anyone who happens upon this post in desperation…

After posting this issue in BuddyPress’s bug tracking system, I was informed that I needed to set:

define( ‘BP_ENABLE_USERNAME_COMPATIBILITY_MODE’, true );

…in wp-config.php

This seemed to resolve some of the issues, but not all of them. For some reason BuddyPress’s theme still seems to be forming the incorrect URIs in some areas.

So, that may help in your case. I’ve actually reopened the issue to see if there’s anything further that can be done…
