"kitchen sink" & all other basic visual editors are gone

I just did the latest WP update and now my visual editor components are gone! plus everything I’ve written is still there but you can’t see it unless you left click and highlight everything and then it’s in white. It’s like everything went invisible.

The visual editor tab is still there but no way to edit. When I click in the edit box the cursor won’t even show up. This is the same for posts & pages.

I’ve checked and the visual editor is NOT disabled under users.

Any ideas? HELP!!
