nach der Neuinstallation

Hallo, ich habe die Basis-Einrichtung erfolgreich abgeschlossen. Auf gleicher Seite habe ich die Links für den Shop-Frontend und Backend bekommen. Nur bekomme ich nach klick auf diese folgende Meldungen, mit denen ich absolut überfordert bin. Kann mir hier jemand weiter helfen? Danke Euch schon mal.
