So recently I’ve had some issues with plugins working. For example I use a Google Analytics plugin that shows my GA stats directly on my WordPress Dashboard. After posting on the WordPress Forum a plugin support member suggested disabling Rocket Loader within Cloudflare to resolve this issue.
How to disable Rocket Loader;
Login to CloudFlare and click on your site.
Go to the 'Speed' tab/icon.
Scroll down till you see 'Rocket Loader™'
Disable the Rocket Loader Option.
Once disabled try your site. If the plugin still doesn't work then clear you cache or try another browser.
Away you go!
