recaptcha giving invalid key error in WordPress

I am trying to use the recaptcha feature in gravity forms on wordpress. It keeps giving me a invalid key code error. I have deleted the site in my recaptcha account three times and re-set it up for the same website each time. Changed the key element in gravity forms settings in wp each time. Still getting the same error message. Any help would be greatly appreciated. -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
