Why isn't my add to cart button redirecting to multilanguage cart page?

[molto]

I have a problem with add to cart product page button

it doesnt redirect to multilanguage cart page (i'm using langshop and they told me its a problem with the code), only to default cart page which is only in the main language

This is exactly my problem too. When I go to cart page, it goes back to the default language. When you change your language on the cart page then you go to checkout, does the checkout being translated?
