I had problem so i had to re install my whole magento site and i exported my products in csv with two method. With Import and With Dataflow - Profiles. I recreated the categories and i try to import the files but it gives error for every single product. "Skipping import row, required field "sku" is not defined." I don't know how could i fix because i have sku for every item.
I tried also the same two method to import. I didnt work out.
Thank you for the help.
Mage::log(var_export($importData, 1))
in Mage_Catalog_Model_Convert_Adapter_Product::saveRow(), it seems that there is where the error is triggered. – Bogdan Constantinescu
