@denysbezu could you elaborate how you made those changes exactly? ... and what they´re doing? Wouldn´t it be easier to find the place where Presta is taking the language information from the Admin from and inject a variable or fixed language? Or maybe thats what your overrides are doing and i just don´t understand them? Where do you define the fixed language?
I´m on Presta 1.7.5.1 and just figured out that for all invoices (customer and BO) ALWAYS (edit: i have to correct me -> attached invoice to payment accepted emails. FO if user is logged in works fine) to the language of the Admin is used. How Awkward.
