WooCommerce

Für die WooCommerce Version 2.X funktioniert das AWS Shipping Plugin aus dem WordPress Repository leider nicht mehr. Im Forum auf wordpress.org hat jemand das Plugin AWD Shipping Costs mit dem funktionierenden Weight Based Shipping Plugin angepasst, so dass es auch mit WooCommerce 2.1 funktioniert. Hier sind die Änderungen

<?php
/**
 * Plugin Name: Weight and Country Table Rate shipping for Woocommerce
 * Description: WCTR is a weight and country based shipping method for Woocommerce 2.1, based on <a href="http://www.andyswebdesign.ie/blog/free-woocommerce-weight-and-country-based-shipping-extension-plugin/">AWD</a> and <a href="http://wordpress.org/plugins/weight-based-shipping-for-woocommerce/">WOOWBS</a>
