When I enable membership 2 all content is blocked on my site. The protection page says "All pages that do not have Content Protection applied are visible to Everyone" But as soon as I flip the switch on the Settings page to enable content protection, the home page (as an example) just shows a white screen with no error.

I've even gone in and created a Public membership and added that to every page. When I do that the error switches to a 500 error.

I removed the Public membership and it states "Everyone" has access, but when I re-enable content protection, I get a 500 error.
