featured image

Hello Skandha, I just bought the theme Travelore. Working with the featured image possibility is really important to us. I dit the next things: -made a new subdomain: ttl.hagmeijer.nl -installed a new Wordpress. -installed travelore pro -made one image 800 x 800 px in one color -made a new page -set the image as the featured image result: page without featured image. Can you please tell me what I did wrong? Kind regards Hans Hagmeijer
