After migrating our eshop to a new server, when i try to import new products, as we did in the previous one, it throughs an error failed code 11 and nothing happens.
EDIT: After further investigation, it throws either a failed code 11 or an error that - Uploaded file is not an zip file.
I checked phpinfo and zip is installed and enabled.
I was not able to find anything about this error. Can you help?
