This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

WP Version in Query String Modifier


Depending on your needs, this plugin is useful for:

  • updating the version value to an incrementing number (with a single click) for cache-busting purposes (this is the default value)
  • removing the version parameter for optimization purposes
  • option to disable modifying the url without disabling the plugin

The author have dealt with issues when the server is running ATS, Varnish or similar cache utility that the author has no control over. Sometimes cache files stick around for a while and users have no control over caching applications. If you want your css, javascript, image or other asset updates to be reflected instantly, this is the perfect solution for you.

The plugin has been tested extensively with WP_DEBUG enabled and works seamlessly with multi-site network setup.
