I've just launched my new website/blog, and all was fine with 3.3.1 on localhost. I moved everything across to my new server ... and all was well.
When I tried to add a new image to the media library, alas WordPress fails somehow in adding this to the Media Library. The item shows in the media library, but with no thumbnail.
When I press "Edit Item", I can see the image ... which is even weirder.
Any help would be greatly appreciated.
BTW, I've tried changing the theme, and it results in the same. I've also tried deactivating all plugins, but that didn't do anything. HELP!!
