I recently updated my client's WordPress to version 3.3.1 and Gravity Forms to version 1.6.3.3.4. After the update, my form is throwing an error on the reCAPTCHA field. I have set up a testing page to show the error:

The form was working fine before the updates. This error seems to show up in different browsers, so it's not specific to one browser.
Any ideas?
