Using the Google PageSpeed Online, it looks like the CSS/Images/JS files of most of my plugins (including wp-nivo-slider) do not get their expires-headers set. Is there a solution for this so that W3 Total Cache will set the expires headers on all the media on my page?

Make sure your hosting provider offer mod_expires. Because many shared hosting providers doesn't offer mod_expires . Just contact your hosting support.


Check if Performance > Browser Cache > General > Set expires header is checked.

  • Yes it is. Using the PageSpeed tool I can see that only the assets associated with plugins are not getting the expires headers set. – GavinR Jun 27 '11 at 21:03
