Visual Editor Stopped Working

The visual editor stopped working on all my WP sites either yesterday or the day before. I can see the tab for “Visual”, but only see HTML. Clicking on Visual does nothing.

I tried disabling all plugins, switching to default theme, deleted cache etc, no luck.

However, I do notice that if I run with Firebug on I am getting lots of JQuery errors. This is what I get when I click on “Edit” when viewing a post…

I do see that a handful of related JS files were changed yesterday, not sure by what though…

In wp-admin/js …

editor.dev.js
editor.js
common.js

I re-installed 3.2.1 so the JS in wp-includes has all been re-updated today.

Any thoughts? I am off to compare the changed js files with the standard ones from a fresh download, and hoping this helps.

I don’t think I have been hacked, at least hope not!

Thanks in advance for any help.
