reCaptcha only working on debugging site

I have a site registered with reCaptcha. It was migrated from another server and address that was using the reCaptcha with an unknown google account. I noticed what had worked on the other site but stopped working after the migration was the pages with reCaptcha. I registered a new reCaptcha with my google account and it works on the debugging site but still does not work on the live site.
