On my post editor, the visual editor tab only shows up blank white. I cannot type in it or use it. The text/HTML editor works. The problem occurs on both old and new posts. The problem occurs in multiple browsers.
My site is http://www.reallifenotes.com
I have deactivated all plugins. I've always only used the Twenty Eleven theme, so that's what's on it now (though I do have a child theme just with a few of my own little changes).
I have cleared the cache several times.
I have reinstalled WP 3.5.1 using an automatic reinstall. I'm not sure how to reinstall manually.
"Warning: Error in parsing value for 'background-image'. Declaration dropped." There are several errors like this with different source files listed. I don't know what this error means.
