Since the automatic upgrade to WordPress 3.5 I can't upload pictures; I only have Visual/Text and only Text is showing, I can't click on Visual. I can't insert pictures. I've tried deactivating all the plugins and manually emptying the cache. It didn't work. I tried that on both my Windows 7, Firefox and on my Mac, Safari. Didn't work. I tried adding a new page with the plugins deactivated after emptying the cache. It still wouldn't let me click on the Visual tab. I'm using the child Responsive Theme. I've tried reaching out to programmers all around to see what they can suggest.
