# Failed to execute 'send' on 'XMLHttpRequest'

 * [11 years, 3 months ago](https://wordpress.org/support/topic/failed-to-execute-send-on-xmlhttprequest/)
 * Installed the new plugin v1.11 on my WP Engine staging site for testing with 
   reCAPTCHA v2 enabled for the Comments form.
 * When using Google Chrome only, the following error is displayed below the reCAPTCHA
   box whenever the Submit Comment button is pressed:
 * `0 NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load'
   https://mysite.staging.wpengine.com/wp-admin/admin-ajax.php'`.
 * Trying it in IE11 displays only:
    `0 NetworkError`
 * then IE11 displays a pop-up dialog “Internet Explorer Security – A website wants
   to open content using the program on your computer”
 * It doesn’t matter whether or not the reCAPTCHA is passed when clicking the Submit
   button, always get the 0 NetworkError message.
 * Oddly, the reCAPTCHA works fine with FireFox with user-friendly in-line error
   messages such as “Error: You have entered an incorrect CAPTCHA value.” and I 
   can submit a valid comment.
 * Access to /wp-admin/ is not restricted, loading the URL in FireFox:
    `https://
   mysite.staging.wpengine.com/wp-admin/admin-ajax.php` displays a simple “0” in
   the web browser.
 * I’m using the latest versions of IE 11, Chrome 39 and FireFox 34.
 * Thanks

 * Is there a way to provide the actual URL to you outside of this forum? The “mysite”
   in the URL is a generic.
 * Thanks
