The Visual and Code tabs do not work. If I turn off visual editor in Users, it does show Code on pages/posts. When I activate visual editor Code and Visual do not work. I have emptied my cache, checked and uploaded /Includes/js with no change. I am using the latest Explorer and everything was working fine until today. I notice that the Explorer and page bottom says, "realTinyMCE is undefined". I uploaded that folder as well with no change.
