Must Use Plugins sind Plugins in WordPress, die immer aktiviert sind und nicht deaktiviert werden können. Sie werden normalerweise verwendet, um Funktionen bereitzustellen, die für das ordnungsgemäße Funktionieren einer Website erforderlich sind, wie z.B. Sicherheitsfunktionen oder Caching. Must Use Plugins werden in einem speziellen Verzeichnis auf dem Server gespeichert und automatisch von WordPress geladen, ohne dass der Benutzer sie manuell aktivieren muss.
