Wenn ich zum Beispiel die FAQ wieder aktiviere, dann erzeugt die alte Installation (und Live-Seite) eine Fehlermeldung:

Zum Glück ließ sich das durch das erneute Deaktiveren der Module wieder abstellen. Hier ist wohl noch mehr im Argen....
Wahrscheinlich liegt es an der Installation von zu vielen Erweiterungen...
