Contact Form 7

Yesterday, I migrated from my development domain to my production domain. I just now noticed that reCAPTCHA is failing in production (busy cursor just spins and spins and eventually issues an error on the CAPTCHA) but works just fine in development. I set up the Google API with both websites and I know it works properly in development. Google is also issuing the following message for reCAPTCHA:
We detected that your site is not verifying reCAPTCHA solutions. This is required for the proper use of reCAPTCHA on your site. Please see our developer site for more information.

Any suggestions on where to look?
