I am running GarageSale 7.0.8b8 (803) and I've been getting an error that I have never received before that prevents me from posting any of the templates.
"Products have a registered UPC. please enter a valid UPC that matches your product."
I have tried closing and reopening GarageSale, refreshing the token, and putting N/A in the barcode section (this was mentioned in another post). So far none of this has worked and I'm not sure how to remedy this problem as it is the first time it has come up. I have tested 3 listings and they all show the same error message.
