Fehler im Installtool

[planepix]

Hallo zusammen,

eine Webseite wurde erstellt und dann umgezogen auf einen anderen Server.

Contao 4.9.22
PHP 7.4.26

Bei Aufruf des Installtools wird nur die Fehlerseite ausgegeben „ Es ist ein Fehler aufgetreten”.

Im Logfile unter /var/logs steht folgendes:

Da ich keinen Zugriff auf PHPMyAdmin habe ( FE und BE funktionieren ), kann ich hier nur um Hilfe fragen, was die nächsten Schritte sind, um das Installtool aufrufen zu können. Danke.

Stelle sicher, dass der Server die empfohlenen MySQL Anforderungen erfüllt und du utf8mb4 nutzt.
