Google reCaptcha says: invalid-request-cookie

Question

This is my first time using recaptcha on my site.

I use PHP API to check recaptcha, it keeps saying invalid-request-cookie

I found out on another forum that www.example.com is different from example.com, so I will register my site again without www , but still it does not work.

When I check recaptcha_response_field and recaptcha_challenge_field , the values ​​are correct.

here is the control panel:

 require_once(recaptchalib.php'); $publickey = "not displayed"; //for security $privatekey = "not displayed"; //for security $error = null; if( $_POST ) { $arr = array('a' => $_POST['task'], 'b' => $_POST['recaptcha_challenge_field'], 'c' => $_POST['recaptcha_response_field']); if( trim($arr['a']) == 'captcha' ) { $resp = null; $error = null; $captcha_result = 'success'; $resp = recaptcha_check_answer( $privatekey, $_SERVER["REMOTE_ADDR"], $arr['b'], $arr['c'] ); if( $resp->error ){ $captcha_result = 'fail'; } echo $captcha_result; } } 

here is the HTML code:

  <div id="captcha-div"> <script type="text/javascript"> var RecaptchaOptions = { tabindex: 1, theme: 'custom', custom_theme_widget: 'recaptcha_widget' }; </script> <div id="recaptcha_widget" style="display:none"><div id="recaptcha_image" style="width: 200px; height: 57px; "></div> <?php echo recaptcha_get_html($publickey, $error); ?> <div class="recaptcha_only_if_incorrect_sol" style="color:red">Incorrect.

can someone help me with this problem?

Thanks Justin

How to support reCAPTCHA :

No, this will not result in an invalid domain. This means that you are not sending recaptcha_challenge_field to the server correctly.

So make sure you visualize the form using recapcha. Check out this link .
