Caching plugins by default will return the desktop version of a site, even on a mobile version, unless you disable caching for mobile devices.

The information that the WP Touch plugin provides at is also relevant here, added below for convenience:

  1. Enable Mobile device support.
    In the Advanced tab of the WP Super Cache settings select “Mobile Device Support”* and click “Update Status”.
  2. Exclude mobile user agents.
    Still in the Advanced tab, scroll down to the “Rejected User Agents” area. Paste the entire list of mobile user agents found below into the field and click “Save UA Strings”.

    MSIE 10.0
    Nexus 7

    Please note: If you have added support for additional mobile devices in WPtouch Pro’s Compatibility > Custom User Agents field, you must also include those user agents in the “Rejected User Agents” area in WP Super Cache.

  3. In the “Contents” tab, click “Delete Cache”  and “Delete Expired” to delete pages that were likely cached before adding the new list of rejected user agents.
  • Enabling “Mobile Device Support” alone seems to cache and serve mobile page separately to mobile devices. If you are seeing issues where mobile pages are being shown in your desktop browser or vice-versa, please apply all the settings outlined above.
  • If you’ve configured WP Super Cache and caching issues persist, try manually removing all cached files from your server via FTP.

Making life easier for mobile site developers:
  • Template functions: to help determine which tier of mobile device (touch/smartphone/other) is viewing your site, to allow conditional content inclusion.
  • CSS Selection: Adds device and tier specific CSS selectors to the body_class, to allow conditional CSS (e.g. so in the same way you have “.single” that you can target “.iphone” or “.mobile-tier-touch”.)
  • Boilerplate mobile theme: barebones theme to enable developers to create their own theme.


  • Switch themes: Switch your theme to a mobile-ready theme if a mobile device is detected (all major devices supported)
  • Tablet or not: Choose whether to switch theme when viewing site with an iPad, Nexus 7 and other tablets.
  • "View full version of this site": allow your user to manually switch between desktop and mobile versions. Available in 3 versions: widget, option to automatically insert into footer, or template tag.
