    Hello @engenheirouva,

    Thank you for your inquiry, and I am happy to answer this.
    Not detected means you don’t use mod_php mode, so you are probably using php-fpm. We cannot detect Apache modules in that case, but that doesn’t mean it is not installed/active.
    I.E. Enable Gzip compression, (mod_deflate is required) check if gzip compression is working (Test your website on GtMetrix or use any other gzip check tool). If it’s working it means that apache module mod-deflate is installed and enabled on your server.
    You can also contact your host and check if those modules are installed/enabled.

    Hello @engenheirouva,
    No, those are just external resources that can not be handled by W3 Total Cache or any other plugin for that matter.

    Thanks.

    Do you believe is that my problem with header expire or I might have set it wrong?

    Any tutorial on this using W3?

    Thanks

    Hello,

    As said in the previous message there is nothing that the plugin can do about external resources.
    AS for other settings, static content (global CSS styles, logos, etc.) – access plus 1 year
    Everything else – access plus 1 week
    I.e.
    Performance>Browser Cache, CSS&JS sub-box Expires header lifetime: 31536000 seconds
    Performance>Browser Cache, Media&other sub-box Expires header lifetime: 31536000 seconds
    Performance>Browser Cache, HTML&HML sub-box Expires header lifetime: 3600 seconds
