Invalid reCAPTCHA request. Missing challenge value

Question

I'm using reCaptcha in an MVC application. In controller i have RecaptchacontrolMVC.CaptchaValidator attribute.

My CaptchaValid always return false with the error message "Invalid reCAPTCHA request. Missing challenge value."

[RecaptchaControlMvc.CaptchaValidator]
public ActionResult Login(Model model, bool captchaValid, string     
                captchaErrorMessage)
 {
   if(captchValid)//this is false
 }

Am I missing something?

Not sure But Re-captcha require 4 fields to verify as stated here. https://developers.google.com/recaptcha/docs/verify

I believe you are missing the parameter "challenge" in your post request. Try to see whats getting passed in HTTPFox or Firebug.

You probably don't have the correct public key/private key combination for the URL that you set up for this Recaptcha control.
