Deactivate WordPress registration – here’s how!

To deactivate the default registration page of WordPress (/wp-login.php?action=register) and at the same time enable registration via WooCommerce, you can do the following:

Add the following code to the functions.php file of your theme or use a plugin for custom code snippets to avoid direct changes to the theme files:

function disable_wp_registration() {
    if (isset($_GET['action']) && $_GET['action'] == 'register' && !is_admin()) {
        wp_redirect(home_url());
        exit;
    }
}
add_action('login_init', 'disable_wp_registration');

This code checks if someone is trying to access the WordPress registration page and then redirects them to the home page (or any other page you prefer).
