Error when loading functions child theme

Hi,

I’ve a Enfold child theme running, but when uploading the functions.php file the site crashes. I’m using some custom functions, which works fine for other child themes. Any suggestions what can cause the problem>

<?php

// Remove WordPress Version Number in head

remove_action( 'wp_head', 'wp_generator' );

/** BACKEND */

// custom WordPress login url

function wpc_url_login() {

return "http://www.woutervanderzee.nl";

}

add_filter( 'login_headerurl', 'wpc_url_login' );

// custom WordPress login logo

function login_wouter() {

wp_enqueue_style( 'login_wouter', get_template_directory_uri() . 'style-wouter.css' );

}

add_action( 'login_head', 'login_wouter' );

// custom WordPress Dashboard footer

function wz_footer_dashboard() {

echo 'Een website van Wouter van der Zee, Webdesign, powered by WordPress.';

}

add_filter( 'admin_footer', 'wz_footer_dashboard' );
