A Moodle site is configured with "Force users to login" on. Default language is set to German. English and American are also available in the language popup menu. When one comes to the site for the first time from a given computer, the login page displays in English instead of German. The same if user logs out . Regardless of the user or session language in effect, the login page shows always in English. One has to use the popup menu to switch to German.
