I just added
define(‘SCRIPT_DEBUG’, true);
to my wp-config.php file but still have the same problem.

Another thing that I’ve realized is that as I mentioned earlier, when I add a featured image, the thumbnail that should show on the lower right corner of the screen does not display, but if I refresh the page it will them display in the editor. Still no thumbnails in the add media popup though.

Yeah, it’s interesting. Even though no thumbnail appears, it’s still allowing me to upload and insert images into posts. Whenever I choose to insert into post, the thumbnail is viewable in the editor. If I choose to add it as a featured image though, it doesn’t display the thumbnail in that section of the editor.

I’m having the same problem. I just upgraded from 3.4 to 3.5. I’ve tried 3.5, 3.51, and 3.52. All of my media seems to show up everywhere fine except when I’m creating / editing a post or page and click on “add featured image”. When I do that, none of the thumbnails load on the popup.

I have tried deleting all of the plugins and using the default theme with no luck. Anyone have any ideas what the problem could be?
