Solved!!!
I have changed “has sidebar” in function.php whit “no sidebar”.

Before

function graphy_body_classes( $classes ) {

	if ( is_active_sidebar( 'sidebar' ) && ! is_page_template('nosidebar.php') ) {
		$classes[] = 'has-sidebar';
	} else {
		$classes[] = 'no-sidebar';
	}

After

function graphy_body_classes( $classes ) {

	if ( is_active_sidebar( 'sidebar' ) && ! is_page_template('nosidebar.php') ) {
		$classes[] = 'no-sidebar';
	} else {
		$classes[] = 'no-sidebar';
	}
