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.



IE 7 and 8 don’t do CSS3 or Media queries so instead of adding the fixes to your theme you can add them via a plugin. This means when they finally die a death you can drop support without having to update your theme. This also covers purchased themes so you don’t need to alter the actual files.


  1. Upload the compatiblizr folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Check the options that you would like to include in Settings > Compatiblizr
