powellrd

I have identified the error :

When creating a Flat Rate Delivery Method, there is a zero prefilled in the first “Cost” field. This needs to be removed if completing the “Delivery class costs” filed by eg a formula to charge poer item.

I did not appreciate this previously as for other Flat Rates I had incorrectly inserted a value to the upper cost field, then deleted the value when I realised I needed to insert a formula in the Class field, thus deleting the first value & leaving the field blank, rather than zero.

This is trivial & therefore annoying.

I have had to disable the Shipping Class that was causing the problem in order to launch the site.

I would still appreciate a solution for the future when I may need to re-instate it.
