Using WordPress 3.8 and Graphene 1.9.2, I am getting short blank "posts" after the first three posts in the vertical post display on the home page at http://nicolaus.com.
My post index doesn't show any blank posts and I can't think of what I might have done to generate these blank phantom posts. Might it be a problem in the theme? If so, it's new. I can't say exactly when it began but not more than a week or two ago.
Thank you for your attention to this issue.
