 * Hello,
 * I am trying to log in as a client (front-end) on one of my client’s websites,
   but I get the 403 error for admin-ajax.php. The response is -1.
 * In order to avoid the caching on admin-ajax, I have added the URL on Cache/[4]
   Excludes on the top textarea, and on[5] ESI, I have enabled it and I added some
   actions, but every 24 hours I have to clear the cache to avoid this from happening.
 * Any ideas?
 * Thank you in advance.

 * Hi,
 * this sounds like a typical nonce issue
 * please try identify the nonce name that call used
 * you should see it in http requests header
 * Best regards,
