Hast Du das Shopware-Verzeichnis sowie die Datenbank vor der erneuten Installation komplett leergeräumt? ![](https://europe1.discourse-cdn.com/flex013/uploads/shopware/original/1X/385eaa628505df573ebf33722f780335f53ac1b2.png) Timme Hosting - schnelles nginx-Hosting [www.timmehosting.de](https://timmehosting.de/)
