Just had an email from one of my clients with the following screenshot. They've not had any issues at all until today. I've just applied the latest stable updater to see if it fixes the issue but no joy.
Hi Phil Is this with any particular ZIP or does it happen with all of them? Assuming it's all of them, could you turn on logging in ECT Admin -> Main Settings -> Store Settings and then try getting the USPS rates and then send me the XML request and response from the logs.
Hi Phil Sorry for the problems but I've got a fix for this now and the fix is in the updater in the files... vsadmin/inc/inccart.php vsadmin/inc/uspsshipping.php
