[TYPO3-german] Fehler beim Update von 4.7.7. auf 6.0.0

[Hugo]

Hi,

habe ebenfalls Probleme beim Update einer Testinstallation von 4.7.7 auf 
6.0.1 (bei 6.0.0 war das Problem auch)

Und zwar scheint das Backend zu funktionieren, das Frontend liefert 
folgendes. Bis Version 4.7.7 funktioniert das Frontend allerdings 
problemlos. Hat jemand dazu eine Idee? Ich bin nur so weit gekommen, 
dass es evtl. etwas mit der Rootpage zu tun hat aber was...
