I'm unable to insert any images from the Media Uploader after they have been uploaded.
I select "Add Media" or "Add Featured Image" and they upload fine, but once I click "Insert", they don't.
I thought it might be my theme or plugins, but I've disabled them all and tried using the default Twenty Twelve theme and it still didn't work.
I've also tried adding "define('CONCATENATE_SCRIPTS', false );" but that doesn't help either..
I also tried reinstalling WP. no luck..
Any other suggestions?
