 * Hi,
 * when I try to check my site with i.e. gtmetrix.com, I get his result (sometimes
   too when I try to open the site in a browser):
 * Notice: Undefinied index: HTTP_CF_CONNECTING_IP in (…) /wfUtils.php on line 506
 * I tried to switch in the wordfence options unter “How does Wordfence get IPs”
   to the first option “Lets Wordfence use…”, but i still get the same issue.
 * What can I do? I am using Cloudflare.
 * Thanks a lot!
 * Yours,
    Mario

   get IPs”?
