Tiny MCE popups blank in Django admin

Question

I have got tinyMCE working in the django admin, but all the popups are blank (eg. edit HTML, add image)

The paths to the popup html pages all exist in the right plac

Answer 1

I changed the media from being served from http://thatch.media to be http://thatch/media and now it works

Maybe something to do with being in different domains?
