На моем компьютере запущенное приложение не меняет язык, даже когда я явно указываю lang = en, все отображается с моим локальным языком, независимо от того, что и на другом сервере, расположенном в США, работает то же приложение правильно . Какой способ копать? Что-то связано с системой? Или настройки языка? На всякий случай, Spring config и один из шаблонов
