rt19 v 2.3.2 outdated content-single-product.php file

<?php
/**
 * The template for displaying product content in the single-product.php template
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/content-single-product.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
