 * I am using SG Optimzier and when I run google pagespeed I get a preload key request
   issue with a warning of
    `Warnings: A preload <link> was found for "https://littlediscoverer.
   com/wp-content/uploads/siteground-optimizer-assets/siteground-optimizer-combined-
   js-e6adfba844895d16582bb1ad68e81bb7.js" but was not used by the browser. Check
   that you are using the`crossorigin`attribute properly.`
 * This is only when I enable the defer render blocking JS feature. Please help!

 * You should preload domains and not full URls. Plus, make sure you’re actually
   using it.
