Hi, actually that is the default Italian translation that is provided with Hikashop. I can change it but since it is the default one, maybe it's better to change it in the distribution removing "prodotto" in PRODUCT_QUANTITY language string in the products section. Also PRODUCT_CODE, ...PRICE and ...DESCRIPTION include "prodotto" and should be removed for consistency.
I have checked that the English string do not have "product" so the removal is correct.
Also PER_UNIT_AT_LEAST_X_BOUGHT had a small glicth in Italian.
I submitted the modified file through the backend.
