i've seen this issue written up several times about the plugin, but no resolve. It's unfortunate as the plugin seems otherwise great. What seems to happen after login is it's adding a second folder to the path.
In my case http://imaginationseverything.com/edwards/?page_id=812 it's trying to add a second edwards/ to the path once it's logged in.. thus preventing the user to access the page. If i remove the extra edwards in that logged in path, i'm directed to the exact page i'd want logged in viewers to see. any and all help on this appreciated.
