Blog posts not showing up..hmm

So I have a blog set up at http://www.eatiply.com/category/ateatiply and usually everything works fine, but for some reason about half the times I check on the page, the blog posts are completely gone. Half the time the blog posts are exactly where they should be and nothing is wrong though.

When the blog posts are gone, the layout is still intact with the top bar and the sidebar.

Please help!
Thanks.
