The content localization language switcher doesn’t work on my forum. It is visible, but when you select English, the result is still a German forum interface.

There is no hint in the description of `content_localization_language_switcher` that another setting is required for this to work. The supported locales are configured and show up in the dropdown. The content localization feature itself is enabled too.

`allow_user_locale` and `set_locale_from_accept_language_header` are also enabled.

Do I need to enable `set_locale_from_cookie` or `set_locale_from_param`? Or where is the problem in my configuration?
