I have a rotating featured content box at the top of my blog. For posts that I want to be included in this box, I always upload an image to the 'Featured image' section from my media library. When I publish the post, the picture is there in the featured content box. However, after I refresh the blog once or twice, the picture is missing. Going back to the post, I see the url of the picture is missing from the 'featured image' section.
I re-enter it, but the same thing happens. It's there for a bit, and then disappears. My site is: www.filmandscissors.com/blog
Any help is much appreciated!
