I'm trying to do Recaptcha in my page. I'm checking a demo with the localhost. But, I'm keep getting error as invalid-request-cookie always when checking. I'm following Displaying recaptcha without plugin and Verifying recaptcha without plugin.
Here is my code
<html>
<body>
<form method="post" action="http://www.google.com/recaptcha/api/verify">
<script type="text/javascript"
src="http://www.google.com/recaptcha/api/challenge?k=my_public_key">
<!-- I used my public key -->
</script>
<noscript>
<iframe src="http://www.google.com/recaptcha/api/noscript?k=my_public_key"
height="300" width="500" frameborder="0"></iframe><br>
<textarea name="recaptcha_challenge_field" rows="3" cols="40">
</textarea>
<input type="hidden" name="recaptcha_response_field"
value="manual_challenge">
</noscript>
<input type="hidden" name="privatekey" value="my_private_key">
<!-- I used my private key -->
<input type="submit" value="Ok"/>
</form>
</body>
</html>
In google, I saw that, invalid-request-cookie means The challenge parameter of the verify script was incorrect. But It seems to be correct. Is it right or is there any other mistakes? Someone help please
