  1. Upload plugin file through the WordPress interface.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Go to Settings » CloudFlare Rocket Loader Ignore, configure plugin.
  4. View a page that contains a script tag with one of the scripts you configured, it should contain a “data-cfasync=false” attribute. Other scripts should not.


How do I use the plugin?

Go to Settings » CloudFlare Rocket Loader Ignore and insert filenames of .js files you want the Rocket Loader to not process. Make sure the “enabled” checkbox is checked. One filename per line.

To exclude specific files, use the full filename including the .js file extension. You can also match patterns by using only the filename or parts of the filename. For example, to exclude any .js file containing the name “jquery” (ex: jquery, jquery-migrate, jquery-ui, etc), simply enter jquery. Any .js file that contains the word “jquery” will be ignored by Rocket Loader.

I entered some filenames but don’t see any changes on the page.

I don’t want the admin CSS. How do I remove it?

Add this to your functions.php:

remove_action('admin_head', 'insert_cfrli_admin_css');

This plugin does exactly what it says. It excludes scripts from CloudFlare Rocket Loader by adding the data-cfasync=”false”. All you need to add the JavaScritp files you want CloudFlare’s Rocket Loader to ignore. (Ex: jquery-migrate.js to exclude only that file or ‘jquery’ to exclude any files with the word ‘jquery’ in it.) Kudos to the developer 🙂

Fixed my lazy image loading and shortcode problem. While keeping the best from Cloudflare Rocket Loader combined with W3TC and This plugin really is version 1.0 worthy!
