SilverStripe 3.0.x cheap trick of the week:
If you want to rename a menu item in the SilverStripe Admin Area, because f.e. you find “Security” or “Sicherheit”(since we are german ;)) a too harsh wording and you prefer “Members” or “Benutzer”:
simply override the translation!
Add a lang folder in your project folder and add the language file:
de.yml or en.yml and place your wording:
de: SecurityAdmin: MENUTITLE: Benutzer
