Hallo,

wie finde ich diesen Fehler und wie begebe ich den?

&nbsp;

The options ‘driver’ or ‘driverClass’ are mandatory if no PDO instance is given to DriverManager::getConnection().

Hallo,

ja, der Fehler ist nicht mehr da. Frage mich aber nicht, was der Fehler war und was ich gemacht habe. Es ist schon eine Zeit her, und ich denke, dass ich Shopware neu Installiert hatte.

Hatte vor kurzem den selben Fehler.

Lösung: es fehlte die Enviroment-Datei (_.env_) im Root
