AJAX HTTP error, Code 403

I seem to have an unusual AJAX error, since mine is a code 403 and not 200 or 500 like I see in the reports.

Tonight I updated my Drupal core to 7.14 and then tried to create a new view. Each time I try to select the content type I want to narrow it to, I get this error:

An AJAX HTTP error occurred.
HTTP Result Code: 403
Debugging information follows.
Path: /system/ajax
StatusText: Forbidden
ResponseText:

It won't let me even edit an existing view, when I try to add a footer to an existing view I get this error:
