Breaks with Restricted Site Access

This plugin is perfect for my needs, but unfortunately breaks when using it with the ‘Restricted Site Access’ plugin, which I use because I only need to restrict access to registered members (don’t need complex membership control).

I just see my front page when I go to the Media Library page. Not sure if this is a problem common with other membership plugins, or is there’s another simple one that this works well with..?
