Hi Cyril, thank you. I am very glad.
I do not use duplication
I am using the language typo plugin fo language filter.
I have "title_en" for ENG language, "title_ru" for RUS (etc.)
But...
I click my button "Add to cart" and
I only have value "title" (column 'title' from table #__content) in my CART and ORDER (column 'orderitem_name' in table #__j2store_orderitems)
I want to have value "title_en" for ENG language, "title_ru" for RUS (etc.) in my CART and ORDER
Is it possible? How?
