I need to do the following on my Drupal 7 site:
- Anonymous users should see the website in Ukrainian (I mean not the content, but the elements like "Login", "Register" etc.)
- Administrator (the user with all permissions) should see the admin panel in English.
- Editor (custom created user that can create pages) should see his admin interface in Russian.
I suppose it can be done with a per-user language setting, but I cannot find how to do this. I already have all the translations installed.
