If you use “Super Page Cache for CloudFlare” plugin, you might be interested in removing its “WordPress Guides/Tutorials” widget from your WordPress dashboard in order to improve its loading time and reduce outgoing HTTP requests.
This can be done with a one line of code which you can add to the theme functions file of your WordPress website or in a must-use plugin:
//Remove dashboard WordPress Guides/Tutorials Widget added by Super Page Cache for CloudFlare plugin.
add_filter('wp-cloudflare-page-cache_load_dashboard_widget', '__return_false');
