Featured Image

Hi…I’m having trouble with setting a featured image for a post written on 11/7. I have other that I post with no problem but this one, no matter what I try won’t show. I’ve deleted the image off my post and from my media library and then I add the image back. I’ve done this a few times, thinking that refreshing it might be the solution but clearly it isn’t.

Any guidance would be much appreciated.
Thanks!
