It happens on PRO 6.4.19 & 6.5.1 (WP 6.5.5). Using ACF, loopers & providers. This archive used to work just fine (I’m not sure when it broke). When I create a new post, the archive page will not show the featured image (it’s broken). Things look fine on the post. So I took an old post, and edited it with the new information, and that seemed to work to display an image on the archive, but it was the old image! The post looks correct, although it carries the old slug. I cleared the Cornerstone cache, the Siteground cache, and looked on a different browser. I deactivated Siteground’s optimizers and other plugins. This is crazy because all the other items on the post can be easily changed and show up right away. Now what? More troubleshooting: Cannot remove or set a featured image on a post.

Elmo’s Fire is an old post that works fine.
Fireball’s Kasper1 is the new post that is broken.
Fireball’s KasperOrds is where I took an old post (Ordonnanz) and changed the info and photos. Individual post looks fine, but the archive photo is the old photo!
