I've looked at this tonight and there is something very crucial that needs an answer. Are you redirecting the author links to XenForo? This is important to overcome the limitations of user_nicename in WordPress. WordPress builds the link to its author URL by using user_nicename, set by XenWord as $visitor['username'];
WordPress will strip out any spaces so that the author URL is built.
This is why my question is very important. Are you using the link XenWord creates or are you relying on the link built by WordPress?
