I have installed Google reCAPTCHA on my local Drupal 7 site and have configured the keys appropriately and set it to run only on the registration form.
I keep getting the error:
Google reCAPTCHA does not accept this submission. Try again please, or contact to Site support services.
I'm not sure why this is happening, I have tried both on my local server and on a hosted production site and I get the same error message.
Anyone know why this is? Or is there an alternative way I could prevent bots from creating spam registrations?
