function add_theme_stuff() {
    add_theme_support( 'title-tag' );
	
	add_theme_support( 'post-thumbnails', array( 'post', 'page' ) );
	add_theme_support('post-thumbnails');

	add_post_type_support( 'page', 'excerpt' );
}
add_action( 'after_setup_theme', 'add_theme_stuff' );

function add_theme_stuff() { add_theme_support( 'title-tag' ); add_theme_support( 'post-thumbnails', array( 'post', 'page' ) ); add_theme_support('post-thumbnails'); add_post_type_support( 'page', 'excerpt' ); } add_action( 'after_setup_theme', 'add_theme_stuff' );
