[TYPO3-german] Fehler beim öffnen des Extension Managers nach update von 4.7.19 auf 6.2.3

[Jan Schreier]

Liebes Forum,

ich habe eben versucht, meine Umgebung von 4.7 nach 6.2. Dabei hat alles prima geklappt. Im Backend komme ich jetzt aber nicht in den Extension Manager, sondern erhalte unten stehende Fehlermeldung. Einen ähnlichen Fehler erhalte ich auch, wenn ich das Install-Tool über's Backend aufrufe. Wenn ich das install tool aber über domain.tld/typo3/install/ Aufrufe, erhalte ich keine Fehler und das Install-Tool beschwert sich auch nicht.
Die Vermutung, dass es ein OpCache Problem ist, konnte ich schon wiederlegen. 

Würde mich über Tipps freuen. Merci! Jan
