That's what you get for naming a class instantiation after the class name:

  lcd.print(DHT.humidity, 1);
  lcd.setCursor(9, 1);
  lcd.print("T:");
  lcd.print(dht.temperature, 1);

See how one is upper case and the other isn't? Pick a decent name like "tempSensor" or something for your sensor object and this won't happen again.
