I am having the same problem using the catch everest theme. I have 4 posts which are “published” and I have my posts page set to an active, published page but when I load that page the content area is blank. None of the blog posts show up.
I know the posts are active though, because they link to the homepage slider and I can access each post by clicking on the slider.
My page is http://www.sacwinterfest.org/. The page called “Winterfest Blog” should be displaying the 4 posts.
