Yes, that box is checked. But actually it’s not the thumbnail that is the problem. It’s the actual post page that shows the large size image at 500×375 (I want 500×500).

Thanks. Yes, I did.

Thumbnail size = 150×150
Medium size = 500×500
Large size = 1400×1400

But this doesnt seem to have any effect on the problem Im having.

It must have something to do with “Path to Full-Size Image (500×375)” under Gallery Post Settings on the New Post page, but I cant find out where to change this setting.
