Clearfy for WordPress: Disable WordPress Features
WordPress has a ton of useful features for beginner and more advanced users. You may not want to take advantage of every feature it has to offer. Clearfy for WordPress is a handy plugin that lets you disable various features. You will be able to disable embeds, emojis, XML-RPC, and RSS feeds. You will also be able to remove author archives, attachment pages, jQuery Migrate, and the admin bar.
Clearfy, as the name suggests, makes your WordPress site cleaner. It also hides author login and disables plugin and theme updates. It can give you a better handle on comments too. As always, you should do your homework before disabling certain WP functions.
