Some time ago, in the STANDARD templates, we changed the "Product code" to the more universal word "Symbol". That is why we decided to make this nomenclature consistent in the IdoSell administration panel.
From now on, incl. on the product card, instead of the "Code displayed on the details page" you will find the "Symbol displayed in the item card on the store's website" field. We only changed the nomenclature, so the functionality of this field remains unchanged.
