Hello Flynax,
I getting import listing error on both admin panel and website michni.com (front side). I am attaching screenshots too for reference.

Secondly, please tell me what data fields/columns should be set/written in import listing file (CSV or XLSx). Can you provide me sample import listing file format with sample data(CSV or XLSX).
