Title: CloudFlare RocketLoader Breaks Scripts Last modified: August 31, 2016 --- # CloudFlare RocketLoader Breaks Scripts * Resolved [Chris M.](https://wordpress.org/support/users/thinkdeep/) * (@thinkdeep) * [10 years ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/) * Hello there! * Just resurrecting this thread here: * [https://wordpress.org/support/topic/cloudflare-rocketlauncher-breaks-this-plugin?replies=8#post-7998460](https://wordpress.org/support/topic/cloudflare-rocketlauncher-breaks-this-plugin?replies=8#post-7998460) * …specifically your comment: * > Would it help if I would add data-cfasync=”false” to each of my scripts? * I’m not sure if there’s another way around this, but Rocket Loader simply will not work with your plugin. * Thanks for your help! * [https://wordpress.org/plugins/duracelltomi-google-tag-manager/](https://wordpress.org/plugins/duracelltomi-google-tag-manager/) Viewing 10 replies - 1 through 10 (of 10 total) * [icyapril](https://wordpress.org/support/users/icyapril/) * (@icyapril) * [10 years ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/#post-7394515) * Hi; * RocketLoader patches many bugs on HTTP/1.1 which have been fixed in HTTP/2. * Many of the benefits of RocketLoader come from using HTTP/2. In order to use HTTP/2 on CloudFlare all you need to do is enable SSL connections, CloudFlare allows you to do this via Universal SSL and redirect all HTTP traffic to HTTPS. * Above this, Google boosts sites ranking if they use HTTPS. If you can’t use CloudFlare’s Full SSL mode, you can [configure CloudFlare to use Flexible SSL with WordPress](https://jonnyjordan.com/blog/how-to-setup-cloudflare-flexible-ssl-for-wordpress/). * You can then disable RocketLoader and your site should work great. * Thread Starter [Chris M.](https://wordpress.org/support/users/thinkdeep/) * (@thinkdeep) * [10 years ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/#post-7394521) * [@icyapril](https://wordpress.org/support/users/icyapril/): * The reason I use Rocket Loader is because it *does* have an impact on load times. I use [https://gtmetrix.com](https://gtmetrix.com) and I notice a multiple percentage increase (sometimes close to 10%) when I have Rocket Loader enabled. * I have HTTP/2 active: [http://d.pr/i/17Njo](http://d.pr/i/17Njo) * I have FULL SSL on: [http://d.pr/i/1d1rs](http://d.pr/i/1d1rs) * I’m also on the CloudFlare network (I have the appropriate Orange Clouds on): [http://d.pr/i/1d8ML](http://d.pr/i/1d8ML) * And my domain is SSL / HTTPS. * Still have trouble when I turn Rocket Loader on. * When I turn Rocket Loader **on**, The Google Tag Assistant (in Chrome) says that GTM isn’t active. When I turn Rocket Loader **off**, it becomes active again. * Thread Starter [Chris M.](https://wordpress.org/support/users/thinkdeep/) * (@thinkdeep) * [10 years ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/#post-7394522) * Additionally, when I use Rocket Loader on other sites (without the “DuracellTomi’s Google Tag Manager for WordPress” plugin), I’m able to deactivate Rocket Loader using this script modifier: * `data-cfasync="false"` * I can’t figure out how to add this with “DuracellTomi’s Google Tag Manager for WordPress” though. * Anyone know how? Maybe with a Function in functions.php? * Plugin Author [Thomas Geiger](https://wordpress.org/support/users/duracelltomi/) * (@duracelltomi) * [9 years, 11 months ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/#post-7394732) * Hi Everyone, * I added this attribute into the core, I hope it will help you with Rocker Loader. * Thomas * Thread Starter [Chris M.](https://wordpress.org/support/users/thinkdeep/) * (@thinkdeep) * [9 years, 11 months ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/#post-7394733) * That’s great [@duracelltomi](https://wordpress.org/support/users/duracelltomi/) * So is that live in the current version already? * Plugin Author [Thomas Geiger](https://wordpress.org/support/users/duracelltomi/) * (@duracelltomi) * [9 years, 11 months ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/#post-7394734) * Next version is (really) scheduled to be released next week. * [Watch Teller](https://wordpress.org/support/users/watchteller/) * (@watchteller) * [9 years, 11 months ago](https://wordpress.org/support/topic/cloudflare-rocketloader-breaks-scripts/#post-7394741) * [@chris](https://wordpress.org/support/users/chris/) M., * At duracelltomi-google-tag-manager > “public” folder > frontend.php * 1.
