As admin all pages are blank

When logged in as admin, all of my front-end pages don't appear, I just have the background colour of the site and nothing more. This is with the membership levels still inactive, though I tried it active too and still nothing shows.

Also, in the section in options that has this:

If you have free user registration enabled on your site, select the subscription they will be assigned to initially.

If you are using a paid subscription model - it is probably best to set this to "none".

I only have 'none' showing in the drop-down menu.
