Has there been a resolution to this issue? I was having the same problem:
http://www.johnmanlove.com/
I found that the following CSS property was set to display: none;
.wpcufpn_container.default .defaultflexslide > li
I imagine that this is so that the content loads and then dynamically is set to block. I forced the display to block in my CSS and the latest posts show up again. Is this related to the latest version of WordPress?
