    This function needs to be called inside the admin_init (or init) action, otherwise it will sometimes cause a Fatal Error.

    add_action( 'admin_init', function () {
    		'WPDocs Import the Things',
    		'Lets you import those things',
    } );
    function wpdocs_the_things_importer() {
    	// echo the content of the page for when this importer is called. 
    	// Just like any other admin page
