Hi, I need different languages available for different storefronts, one storefront available only in one language and second in few languages. It seems that languages can be only turned on or off for all storefronts.
I am afraid, yes. You cannot use different languages on different store-fronts
It seems that on Administrator -> Storefronts there are Languages options for each Storefront.
You have to have the language enabled in Administration -> Languages -> Manage Languages.
