I contacted the host and server provider. They said I should change the URL of the site to http://www.michaelgraversen.com – but after I did that I couldn’t see the images in the backend anymore. It only made it worse. When I try to upload a new image it doesn’t appear.
In that case, things are available, but your theme indicates something different, with some extra letters on the url. I do not have the opportunity to solve for you as it is an open source theme we have not programmed.”
