Customers on my website are getting a recurring shipping error which results in a payment being taken, but the order not generating in Magento. Error code is as follows:
"Please check shipping address. Invalid code of "543" entered in RegionID field."
Does anyone know how I can fix this?
Please bear in mind I don't code, I have outsourced my Magento management so I will need to send them the fix.
Look forward to any assistance anyone can offer.
