My site looks fine and is behaving well.
But when I tried to add a page I could add a title and publish it but I could not add text, html, or media. Same with a post. Then I check existing posts. The all look fine on the site but on the edit page there is no text or media. The other weird thing is that the visual tab is highlighted but the text tab is greyed out.
I turned off all my plugins.... no change.
