member sites are not publishing

When I crate blogs for members on my site, they just appear white when published. However, sometimes they do publish.

Also the new ones I create publish, but they are automatically directed to the "protected content page". I don't want a protected content page.

This has never been an issue when I created the other membership blogs.

Examples:

http://www.theonlineretirement.com/actaylor/-- blank white page

http://www.theonlineretirement.com/northof40/ - points to protected content page.

Please help
