Shipping isn't being calculated
I have just migrated a website to a new server and my client is now stating there is a problem with their Powerstore install. The fact that we have just migrated might be a coincidence.
They have said that when a customer try's to buy an item that postage isn't being added to the final price.
Any idea why I might be experiencing this and how to troubleshoot to find out where the issue is please?
Thanks
