 * I’m trying to make the email field not required during checkout. I’m adding the
   following code to my child theme functions.php but get an error:
 * add_filter( ‘woocommerce_billing_fields’, ‘wc_npr_filter_email’, 10, 1 );
    function
   wc_npr_filter_email( $address_fields ) {
$address_fields[‘billing_email’][‘required’]
   = false;
return $address_fields;
}
 * Here is my functions.php file:
    <?php // // Recommended way to include parent
   theme styles. // (Please see [http://codex.wordpress.org/Child_Themes#How_to_Create_a_Child_Theme](http://codex.wordpress.org/Child_Themes#How_to_Create_a_Child_Theme))//
   add_action( ‘wp_enqueue_scripts’, ‘theme_enqueue_styles’ ); function theme_enqueue_styles(){
   wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/style.css’);
   wp_enqueue_style( ‘child-style’, get_stylesheet_directory_uri() . ‘/style.css’,
   array(‘parent-style’) ); } // // Your code goes below // add_action( ‘init’, ‘
   jk_remove_storefront_header_search’ ); function jk_remove_storefront_header_search(){
   remove_action( ‘storefront_header’, ‘storefront_product_search’, 40 ); } add_action(‘
   init’, ‘custom_remove_footer_credit’, 10 );
 * function custom_remove_footer_credit () {
    remove_action( ‘storefront_footer’,‘
   storefront_credit’, 20 ); add_action( ‘storefront_footer’, ‘custom_storefront_credit’,
   20 ); }
 * function custom_storefront_credit() {
 * add_filter( ‘woocommerce_billing_fields’, ‘wc_npr_filter_email’, 10, 1 );
    function
   wc_npr_filter_email( $address_fields ) {
$address_fields[‘billing_email’][‘required’]
   = false;
return $address_fields;
 } ?> <div class=”site-info”> © Ageless Iron
   TV <?php echo get_the_date( ‘Y’ ); ?> </div><!– .site-info –> <?php } add_filter(‘
   wp_nav_menu_items’, ‘add_loginout_link’, 10, 2 ); function add_loginout_link(
   $items, $args ) { if (is_user_logged_in() && $args->theme_location == ‘primary-
   menu’) { $items .= ‘

       } elseif (!is_user_logged_in() && $args->theme_location == ‘primary-menu’){
      $items .= ‘

 * There is an extraneous non-printing character in your wc_npr_filter_email() function
   where shown with the X:
    c_npr_filter_email( $address_fields ) {
 X $address_fields[‘
   billi If you paste the code in Notepad you should see it. Get the code to validate
