Admin->Login, available languages Romanian and English (I deleted the others), registered users can change language, multilingual is on, detect browser language is off. Anonymous (users not logged on) can switch languages meaning "poll" becomes "sondaj" but registered users (editors and admins) can not. Although PHPMyAdmin
in table users_permissions
groupName permName value
so I would expect the Editors group to be able to switch the interface language.
