Yes. I'll describe:When I use the phar file I put it in /include/i18n/ folder, named pt_PT.phar. It works OK.So I uninstalled from Admin panel and then deleted the file from the server.To use the folder I downloaded all languages from crowdin, copied to my Linux server, copied the folder pt-PT to pt_PT under /include/i18n/pt_PT folder.I go to Admin panel and select Portuguese. The flag appears but, on the client side, while testing on another browser, I select pt_PT, the address changes to pt_PT but all text is in english. This only happens when using the folder instead of .phar file.
