[Plugin: WP e-Commerce] Shopping cart error. WordPress database error

There is an error in Version 3.8.8.1
in /wp-content/plugins/cp-e-commerce/wpsc-merchants/GoogleCheckout-XML.php

You need to edit the file /wp-content/plugins/cp-e-commerce/wpsc-merchants/GoogleCheckout-XML.php
Do a search and replace for “sessionind” and replace with “sessionid”

This error only effects those using google checkout
