Restores the Custom Field meta box for the Gutenberg Block Editor.
Update: This plugin currently is not needed, as WordPress version 5.0+ displays Custom Fields natively. Just click the settings button (three dots) and go to Options, where you will find the option to display the Custom Fields meta box. So this plugin still works great, but it is recommended to use native WP custom fields instead.
