Issues with WordPress 3.2.1

Hi. I just updated my website to WP 3.2.1 and now I can’t add hypelinks or tags (trying to do either results in either no response when clicking submit or closing out my post). I have this issue using Firefox, Safari and Chrome on the Mac. I’ve enabled the Twenty Eleven theme which didn’t help.

I’ve checked my PHP and MySQL settings which seem to be fine.

What’s strange, is I checked a client site (running the same version) with the same plugins and theme and no issues. I can’t figure out what the issue could be with my site???

Any ideas? The hyperlinks aren’t the end of the world since I can add them manually in html view, but the tags are an issue.

Anyone else having this problem?
