undefined “HTTP_HOST” and “res” variables found in inc/cdn.php

  • i noticed in our debug log these errors that keep appearing over and over. I believe that these appear when the cache is cleared. What is this exactly?

    [14-May-2019 04:10:10 UTC] PHP Notice: Undefined index: HTTP_HOST in /home/home_site/public_html/wp-content/plugins/wp-fastest-cache/inc/cdn.php on line 137

    thanks

    it means that $_SERVER[“HTTP_HOST”] is not set. this is a big problem in your site.

    we checked our phpinfo plugin and it is set in the information on the site. is it possible that this is affected by cloudflare? we have cloudflare set up on our site qs well

    thanks

    can you remove the Cloudflare integration and add again please?

    i did not check anymore with disabling cloudflare. i checked the plugins we’re using for displaying phpinfo() details and they are returning the contents of $_SERVER[“HTTP_HOST”] correctly even with cloudflare enabled. Aside from that, one of the plugins has an email functionality which sets up the headers like so

    $headers = array(
    ‘Content-Type: text/html; charset=UTF-8’,
    ‘From: ‘ . get_bloginfo( ‘name’, ‘display’ ) . ‘<no-reply@’ . $_SERVER[‘HTTP_HOST’] . ‘>’
    );

    the ‘From’ in the received email displays the content of $_SERVER[‘HTTP_HOST’] correctly. Since this is in the cdn integration section of wp fastest cache, i just removed the cloudflare integration and changed the cloudflare settings manually in our cloudflare setup based on the options changed by wp fastest cache

    thanks
