When certain archive blog posts show up on a page created from a category menu, or on the blog page showing all posts, the first few (8) images (featured images) show up in the list, then all the rest show no images, but just the text and the more links, with a big space where the image is supposed to be. Refreshing the page does not make them appear, but when the “more” button is click/pressed it goes to the individual post with the featured image intact. I’ve read that there is a “default” number of 8 posts determined somewhere by WordPress, but if that is the problem, how do I change that? I’ve regenerated thumbnails and am stumped about what else to do.
This website has been in effect since 2013 and Generate Press has been used for most of that time. Here’s a sample page:
