When I'm logged out, everything works fine. When I'm logged in, I'm unable to visit the front-end of my site.
My main page is actually located in a sub-folder of my multisite installation: http://beta.eamann.com/mindshare/. I'm mapping a domain to this installation: http://mindsharestrategy.com/. When I'm logged in, the front-end of my site keeps bouncing back and forth between these two domains. I can still get to the admin side just fine ... but not the front-end.
If I log out, I can view the front-end of things just fine.
I'm using the development version of the plug-in, as I was instructed to do by several conversations with the developers. Ideas?
