Membership Options Page not showing created pages

I have selected the 'CREATE PAGE' button in each section of the Membership Page Options, but when i click 'view page', nothing loads.
I get a broken page with a notice saying 'This webpage has a redirect loop'.
The pages are created - ive checked in the pages section of wordpress. But even there i cant see the page if i go into them and select the 'view page' option.

Sorry, im very new to all this and trying to feel my way around in the dark, so apologies if these questions have already been asked (i did search here, but found nothing)

Many thanks
