This seems to have happened rather suddenly: my admin panel has broken.
I was working on a plugin the other night, checked everything made sure it was all working, I uploaded it, checked everything was working and it all seemed fine.
Then today I find my admin panel is completely broken: http://i.imgur.com/Mklzo.png
I disabled all plugins, including the one I've uploaded and it's still broken like that. The thing says 'done but with errors on page' and I'm suspicious the javascript is not working because the errors are and I also get 'This widget requires JavaScript' in the pain admin page:
