I added this topic to the forum, but I thought I'll post it here too. I download, installed, added the Google recaptcha API's and enabled the HS plug in. My registration page displays an error:
Input error: Invalid referer.
I've set the recaptcha to appear below the email, then below the text. It's gives the same error. i'm running your free version while we are in dat-dev. We will be upgrading to your pro version in April, until then we'd like to stop the spamming during beta testing. Please advise
