I've fresh-installed a WordPress 3.2.1 on my server yesterday. Unfortunately, installing 3.2.1 breaks all the jQuery scripts and I can't click on "Collapse menu", "HTML" in the editor, "Fullscreen" - basically, everything that's loaded with jQuery.
I've tested with Safari, Firefox and Chrome on a MAC OS X.
I downgraded on 3.2.0 and jQuery is working properly on this version, but when I upgrade back to 3.2.1. everything breaks.
If you think it's related to JSON, JSON is working properly with PHP, too. I also don't have any plugins installed, except Akismet and the theme installed with the default one: Tweenty Twelve or smtg.
Can anyone help me? Thank you.
