Hi,  
wollte mir gerade einen neuen Shop erstellen. Leider bekomm ich immer wieder diese Meldung

> Fatal error: Uncaught TypeError: Argument 1 passed to Shopware\Recovery\Install\DatabaseFactory::createPDOConnection() must be an instance of Shopware\Recovery\Install\Struct\DatabaseConnectionInformation, instance of \_\_PHP\_Incomplete\_Class given, called in /var/www/xxxxx/html/recovery/install/src/app.php on line 72 and defined in /var/www/xxxxx/html/recovery/install/src/DatabaseFactory.php:41 Stack trace: #0 /var/www/xxxxx/html/recovery/install/src/app.php(72): Shopware\Recovery\Install\DatabaseFactory-\>createPDOConnection(Object(\_\_PHP\_Incomplete\_Class)) #1 /var/www/xxxxx/html/recovery/install/index.php(74): require(‚/var/www/xxxxx…‘) #2 {main} thrown in /var/www/xxxxx/html/recovery/install/src/DatabaseFactory.php on line 41

Ich finde leider den Fehler absolut nicht

Danke schon mal 🙂

Hm, alle Dateien sauber installiert? Mal eine andere PHP Version ausprobiert? Dateien per FTP auf den Server geladen oder von ZIP installiert? Welche Shopware Version?
