  • Try the “Browser Cache” tab of W3TC. It contains “Expires header lifetime” edit boxes. Default “Expires header lifetime” values :

    for “CSS & JS” and “Media & Other Files”
    31536000 seconds [1 year]

    for “HTML & XML”
    3600 seconds [1 hour]

    (For reference, 1 week = 604800 seconds)

    Hello tgeorge

    I still have a problem after changed the recommended timings specified above.

    Here is the result

    What i have to do now?

    Go to the “Browser Cache” tab. Use the following settings for both the “CSS & JS” section and the “Media & Other Files” section :

    [check] Set expires header
    Expires header lifetime: 31536000 seconds
    [check] Set cache control header
    Cache Control policy: cache with max-age

    Don’t forget to save settings, and to click on “Re-Test Page” on the GTmetrix site.

    Hello tgeorge

    I did as you suggested, But still has same problem. Here is htaccess code


    gtmetrix report

    Hmm… It should work. I have exactly the same “Browser Cache” settings, and I get no GTmetrix errors for my site. This maybe means that your webhost does not support the mod_expires module (which is required by W3TC’s “Browser Cache” feature). I know almost nothing about modules, but here is a description :

    “mod_expires module is responsible for setting of the Expires HTTP header and max-age directive of Cache-Control HTTP header in server responses.”

    You should ask your webhost whether mod_expires is supported. If it’s not supported, you’ll have to forget about the “Browser Cache” feature. Sorry.

    Hello tgeorge

    when i inquire with server management team, they said that mod_rewrite is already activated in the server.

    Note : I have used rackspace cloud to host media files. Media files hosted in sub-domain of

    But WordPress installed in

    Is the problem due to image hosted in another domain name?

    Hello Frederick Townes

    I am keenly awaiting for you valuable suggestion to get rid of this issue.

    Hope you might reply soon.

    Sorry, I have no experience with sub-domains. It is possibly the cause of the problem. In fact, you can make a test, by moving one or more images from your sub-domain to your main domain. See whether they disappear from the “Leverage browser caching” list. But I can’t help you further, because of my lack of knowledge. I hope someone else helps you.

    Your failures are mostly subdomains. Any failures for your main domain name are either because you haven’t actually deployed your browser cache settings and are in preview mode or because mod_expires or another required module isn’t installed or enabled in apache.
