Im using the latest version of magmi on my installation (magento 18.104.22.168)
When I run a import to update a single attribute it stops on 1.
It also says 'Initialized attribute_set_infos!'
The file im tyring to import is simply 2 products to test. With headers 'sku' and 'order_code' (.csv file with UTF-8 formatting.)
sku,order_code testproduct,TEST 9015-2160,TU05122
I know this is a Magmi issue and not exactly Magento but I always get good support from this community and I have used the magmi tag. Thanks again
