I've installed a site, and let the client edit the pages with the admin user.

All the sudden I'm not able to add blocks to the page anymore. When I try to add block to a page, the add block box says "Set area permissions". Why? How do I turn i back to normal? (See screenshot) Doesn't matter what i set the permission to. I never get past the permission-editor.

I'm also not able to publish new pages with this admin superuser. The page is being created, but it's now viewable in menu/lists.

It worked ok if I create a new user and asign the administrator role, (although this user doesn't have "admin" permissions to alter "page default".
