I have an html form with a recaptcha image that posts to a python cgi script. The form elements are captured (they print to the form) with the exception of the recaptcha challenge/response, which always appear empty on submit.
The form was working only a short time ago and I've made no changes to apache2 or to my LAN or firewall since then. I understand that I can insert an error parameter into the challenge/response api, but I can't find an example in google docs.
Let me know how to fix this thanks
