Protected Content breaks blog when switched on

Hi Guys,

I am having an issue where my blog posts all disappear from the blog page, and are replaced with a listing of pages on the site, when I switch on protected content.

I have tried disabling all memberships and add-ons, but the blog page is still broken when Protected Content is toggled on.

Site is

Screen1 is how it should look
Screen2 is how it looks with PC on

Any pointers?

Kind Regards,
