Woocommerce Category Title = first product

This comes up from time to time. Try this code to modify the title:

<?php
  // Change Shop page title
  // code goes in functions.php for your child theme
  // used for themes that use a product title for the shop page title
  add_filter('post_type_archive_title', 'shop_page_title' );
  function shop_page_title( $title ) {
    if( $title == __('Products', 'woocommerce')) {
      $shop_page_id = woocommerce_get_page_id( 'shop' );
      $page_title = get_the_title( $shop_page_id );
      return $page_title;
    }
    return $title;
  }

I have tried this php code.

However, I am not sure if I am coding it incorrectly. This is what I have in the child theme functions.php

<?php
add_action( ‘wp_enqueue_scripts’, ‘appointment_blue_theme_css’,999);
function appointment_blue_theme_css() {
wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/style.css’ );
wp_enqueue_style( ‘bootstrap-style’, get_template_directory_uri() . ‘/css/bootstrap.css’ );
wp_enqueue_style( ‘theme-menu’, get_template_directory_uri() . ‘/css/theme-menu.css’ );
wp_enqueue_style( ‘default-css’, get_stylesheet_directory_uri().”/css/default.css” );
wp_enqueue_style( ‘element-style’, get_template_directory_uri() . ‘/css/element.css’ );
wp_dequeue_style(‘appointment-default’,get_template_directory_uri() .’/css/default.css’);
}

?>
<?php
// Change Shop page title
// code goes in functions.php for your child theme
// used for themes that use a product title for the shop page title
add_filter(‘post_type_archive_title’, ‘shop_page_title’ );
function shop_page_title( $title ) {
if( $title == __(‘Products’, ‘woocommerce’)) {
$shop_page_id = woocommerce_get_page_id( ‘shop’ );
$page_title = get_the_title( $shop_page_id );
return $page_title;
}
return $title;
}
?>

I have also added the following code to the end of the styles.css

.archive #intro.option1 h1.page-title span {visibility:hidden}
.archive #intro.option1 h1.page-title:before {content:’Shop’}

Any other ideas or have I implemented it incorrectly? Whilst I have programmed in HTML and javascript for a long time, I am new to wordpress and php.

Where am I looking for the problem? Page looks ok.
