Unable to switch between visual and HTML

Have you tried:

– switching to the Twenty Eleven theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

– re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.

Switching to 2011 and resetting the plugin folder didn’t work. I can’t re-upload here at work, I’ll try that when I get home. I did do a re-install from the updates page. I’m wondering if this may be a tinymce issue (although there haven’t been any changes I’m aware of).

It’s not a 3.3.1 issue. Both editors are working fine in my dozen or so 3.3.1 sites.

I checked in IE (was using Chrome) and saw a warning icon. The errors are:
Line: 2
Char: 1
Error: ‘tinyMCE’ is undefined’
Code: 0
and the URL of the site. The next error is the same thing but Line 1049 The final error is line 1246 Char 3 Object required.

Could be the result of a bad upgrade. Re-uploading the wp-admin and wp-includes should fix that.

No upgrade was done prior to this occurring. Still, I will try that when I get home this evening.

In checking the error logs I see this:

Try contacting your hosts. It looks like a server configuration issue.
