We are having a very frustrating problem with Woocommerce import. We have class module and we just encountered this problem recently after several times of doing import without any issue. I have different csv files from different suppliers but almost have the same content which I use to import the products with no issue.
I have included the source code to check if someone out there could let me know if what are we missing here
thanks
This suppliers datafeed csv file: feedfile
Woocommerce Connector Class file is connectorclass
