Hello. I`m a painter and uses my blog as a personal site. I have always submit my posts as a photo. Suddenly there has appered the problem: post-thumbnail Images ceased to appear on the home page. You can see only Images names on the home paige (I mean "All paintings" category) and only after entering in any post - you can see the image. The problem has appeared a month ago and only new posts are exposed to this. All the posts I make earliar still appears propertly. How can I fix it?
