 * Hi, I hope this message finds you well!
 * With PHP 8.4 and your plugin I noticed the following error:
 *     ```wp-block-code
       PHP Warning: Undefined array key "HTTP_HOST" in /wp-content/plugins/fastpixel-website-accelerator/inc/url.php on line 190
       ```
   
 * I don’t’ know if this is an error about PHP 8.4 compatibility.
