Thanks for the great theme.
I try to import the dummy content, but so far no luck. It does not seem to import anything.
Likely because file permissions need to be set. Could point which permissions on what folders need to be set?
It looks like you have some problem with your server configuration. CSS files can’t be loaded because of 403 Forbidden error http://www.thechocolateshop.nl/wp-content/themes/basel/style.min.css Try to contact your hosting providers to solve this. Solving CSS problem probably will solve Import issue also.
