Hi,

ich bekomme leider einen Fehler bei der Installation.  
Ich habe einen dedicated Server mit PHP 7.3 und MySQL 5.7.26. Das sollte über den Systemanforderungen liegen. Was kann ich machen ?

Error

Received an error message.  
**URL:** importDatabase

Please try to fix this error and restart the update.

Das ist aber Shopware 6?

Je nach Hosting kann das aktuell am Installer liegen, siehe:&nbsp;[https://issues.shopware.com/issues/NEXT-4072](https://issues.shopware.com/issues/NEXT-4072?_ga=2.193909999.333022990.1565790299-345959159.1565790298)
