With a recent update, the recent posts images are missing their default image that I set up with css. Posts without thumbnail images are given class .has-post-thumbnail instead of .no-post-thumbnail (as they were before). I want it to display a default image when no featured image is set. Here is my CSS. Why are posts without a thumbnail image now being given the class “.has-post-thumbnail”?
/*add default image to video post without featured image. */
.x-recent-posts .no-post-thumbnail .x-recent-posts-img:after {
background-image: url('http://SITE.com/wp-content/uploads/2016/03/blog-no-featured-image.jpg');
background-size: cover;}
