Advanced Theme Switcher Apparent Conflict with Member Premium

I’m not sure what to make of this but after installing Advanced Theme Switcher all of my pages redirected guests to a protected page message. We have Member Premium installed and are currently setting it up. It is not enabled. I then deactivated the Member plugin and the protected pages error continued to occur. It wasn’t until I disabled the theme switcher that everything came back.

I tested this multiple times with the same results.
