After adding a needed code and uploading the config files, I can see the language switching bar in admin dashboard and even the access Coalition settings with different languages. My default language is Finnish and I also have English and Germany installed. When I first update Finnish options everything seems to be well: the English pages show translations of Finnish files. When I try to make changes in English or German options, all the options get overrided. The problem seems to be, that whatever language is selected in admin tool, the settings are updated for all the languages. In the same moment, even the pages lose their relations and no translations are shown.
