Problem fixed by setting Maximum execution time for each scan stage to “12”.

Tried 50, 30, 15 and it doesn’t work. Fixed it on “12”.

Siteground.

Both sites are now fixed. I did Flush Cache (static cache, dynamic cache and memcache) on my hosting and all is fine now.

Thanks for the quick reply.

I made an experiment.

I created post4 with no featured image.
I created post5 with image2 as featured image. Uploaded the image from post5 creation.
I created post6 with image2 as featured image.

Then, I edit post4 to use image2 as featured image.

I deleted post4 permanently. Both post5 and post6 still have image2 as featured image.
Now, I deleted post5 permanently. Post6 no longer have a featured image as image2 was deleted with post5.

So here’s my conclusion. When I upload an image and use it as featured image from within a post (post5), that image2 is associated with post5. When post5 is deleted, so is image2.

Temporary solution:
Upload image3 from Media > Add new.
When image3 is uploaded, it’s not associated with any posts.

Now, I created post7 and use image3 as feature image.
I created post8 and use image 3 as featured image.

Then I delete post7 permanently. Post8 still have the featured image.
I deleted post8 permanently. Image3 is still found on Media Library, and still can be used on future posts.

Problem is resolved on my website and a new fix is on it’s way.

Thank you very much ??
