3.9.2 auto-update – Visual Editor Useless

Is there a fix for this? I don’t remember setting my install to auto-update either so I wonder if a previous version set that FOR me?

Basically I’d like to know if there are any ways to get the Visual Post editor back so I can post new content.

The only post claiming to be a fix for some but did not work for others is to download and completely reinstall WP? I am not interested in that. Since so many people out there are having visual editor issues after this update it seems like a fix could be sent out instead?

OR If someone can help me roll back to the prev WP version (I’ve never done that!) I will take that too I guess. Thanks for any help I can get!
