Hi, I can see 3 URL's in the source code of your page starting with http:// instead of httpS:// which causes mixed content.
http://xn--butikkenvedhjen-hub.dk/dir/ http://xn--butikkenvedhjen-hub.dk/dir/da/stores
http://www.butikkenvedhøjen.dk/dir/cookies.html
You should check your website files or editor to see where these URL's are exactly added. Then change the URL's to httpS://
