    Hi, these 2 errors are found after I preload the urls

    • link rel=preload must have a valid ‘as’ value
    • The resource url was preloaded using link preload but not used within a few seconds from the window’s load event. Please make sure it has an appropriate as value and it is preloaded intentionally.

      • How do I fix it?

    Autoptimize simply adds those preload links for every comma-separated URL added in Settings -> Autoptimize -> Extra -> Preload, so you could just add https://bizsphere.com.my/wp-content/plugins/vc-extensions-bundle/css/admin_icon.css?ver=5.5.3 there as well?

    This has already been added in the first place. All are working just this specifically is not working.

    well, “work” it does, as this is in the HTML:

    
<link rel="preload" href="https://bizsphere.com.my/wp-content/plugins/vc-extensions-bundle/css/admin_icon.css?ver=5.5.3" as="style">

    but here as well that’s all AO can do, it’s a “hint” for browsers to preload, if it is preloaded and if it used and if it is useful is not something AO can ensure.

    Typically preloading CSS/ JS/ Images is only useful if the resource is loaded by javascript shortly afterwards, so if that CSS is not loaded by some JS-code or if it is loaded late (no idea what the threshold is), it is useless to have it preload in the first place ..
