Thank you Ray for responding. Instead of recording customer data in the database, could the shop work with only variables or data stored in sessions?
There is one chunk of code on the confirm page after // WA eCart Store Cart Summary in Db
I commented out that code hoping it would not store any customer data in the database, but that produced a blank checkout success page. The error codes didn't help me any.
So my question, is it possible to skip recording any customer data in the database?
