Sorry, we're unable to load this blog.

I have been trying to update my blog, but even after publishing the page where the blog should appear displays a message stating "Sorry, unable to load this blog." I've inserted and reinserted the blog element, have added a blog post, have edited previous blog posts, published them, but still keep getting error message when I try to view the blog. Please help. URL for the blog is http://www.manymoonsdesign.com/MMD-Blog.html.
