Kann mir jemand weiterhelfen mit den Fehlermeldungen. Irgendwie scheint $connection keine Objekt der Klasse DB zu sein. Wobei $connection = DB::connect($dsn, true) erzeugt wird, aber eben mit der Meldung; Error: "Non-static method DB::connect() should not be called statically" (error #2048).

Vielen Dank

Gruss,Jörg
