W3 Total Cache Not Working Correctly

  • I have the W3 Total cache and I can’t seem to get it to work properly:

    1. Add Expires headers, Make fewer HTTP requests,Compress components with gzip, Serve resources from a consistent URL (marked high priority on YSlow, but not working),

    2. Compatibility is okay, but I have things that are required for certain things to work and I don’t know where to find them:

    Installed: Functionality will work properly
    Not detected: May be installed, but cannot be automatically confirmed
    Ok: Current value is acceptable.
    Yes/No: The value was successful detected.

  • When you say that something is “Not Working” it is impossible to provide any help. The compatibility section simply helps you determine what features of the plugin you can use and is totally dependent upon your server / hosting environment.

    To get the best use out of this or any plugin you need to read over the documentation and go through the settings and if you don’t understand a setting after reading the faq and docs then come here and ask a question.
