The other day I updated WP to 2.8 and since then whenever I go to the editor the main window with the code is greyed out and I'm unable to edit any theme files.
Playing around abit I managed to get the editor to go back to normal by disabling all my plug-in, however I then re-activated one of the plug-in (Akismet) and now I have the same problem again where the editor is greyed out and won't let me edit any of the files. Disabling the plug-in again has not fixed the issue this time around. All plug-in are up to date but they are all de-activated and I'm still unable to edit files.
This is the same no matter what theme I activate.
Any help would be appreciated :)
