you don’t need any plugin.just add this code to your function.php file which you will find in your theme folder.

add_action( 'init', 'blockusers_init' );

function blockusers_init() {
    if ( is_admin() && current_user_can( 'subscriber' ) ) {
        wp_redirect( home_url() );
        exit;
    }
}
