    I just fired up a new Lightsail instance in AWS to replace my old one so I can run a newer OS with more modern PHP version. This runs a bitnami layer to manage the web.
    After restoring my web site to the new server, I ran the W3TC Compatibility check and it shows that many modules are not available.
    I checked in my httpd.conf and confirmed that the models are enabled (not commented out) and I have restarted the server since they were uncommented. I can also run the command sudo /opt/bitnami/apache2/bin/apachectl -M to see all active modules and I see certain modules listed as enabled that are showing “Not Detected” on the compatability test. Some examples of the ones I see in this bitnami query are:
    deflate_module (shared)
    env_module (shared)
    setenvif_module (shared)
    rewrite_module (shared)
    expires_module (shared)
    headers_module (shared)

    Since it looks good on Bitnami/Apache side, is there a known issue or something I might be missing that is keeping W3TC from seeing these as enabled?

    Hello @crazyadmin-1

    Thank you for your inquiry and I am happy to answer.
    Not detected means you don’t use mod_php mode, so you probably use php-fpm. We cannot detect Apache modules in that case, but that doesn’t mean it is not installed/active.
    Thanks!
