My visual editor (and HTML editor) buttons have disappeared on all three of the sites I'm working on.
Two use 3.4.1 and one is running an old version of WordPress 3.3.2.
All versions I have lost the editor capabilities somewhere between yesterday morning and yesterday evening.
I've searched threads and tried everything (cleared out caches, tried different browsers, reinstalled WordPress, deactivated and reactivated plugins and even deleted some, changed the user settings).
Is there anything anyone out there can tell me about this? Is this a common occurence? Any help is greatly appreciated!
