Hi,
I think I figured out what is going on, but let me ask you a few questions first…
1. Where do you get images that appear after the post title? Do you use some special plugin to generate thumbnails for featured images on the front page?
From what I can see they’re thumbnails loaded from temporary folder wp-content/uploads/et_temp/
and don’t have the same attributes set as other images in your post and hence we cannot figure out which was the original image nor find the thumbnail of the original image.
2. Were these images added later to existing posts?
For example, this post has related-post thumbnail, but it was not generated from the first image in the post, but the second one. That made me think you added the first image later.
There are two things you can do right now:
- Remove first (problematic) image from posts without thumbnail, update the post, let our plugin generate the related post thumbnail from other image, that was added to the post through Media Library. Afterwards you can add the (problematic) image back.
- Upload thumbnail images that were generated for featured posts to Media Library and add them to your post through the Library, this way our plugin will be able to get attachment id and find/generate proper related post thumbnail.
I know it’s not perfect solution, but it might work until we figure out how to deal with this rather specific issue.
Best,
Mateja
