You only need 1 parent for your page, www.cretinhop.net as there are no other iframes that the embed is within, and if you go to cretinhop.net it appends the www. anyway.
The reason it’s not working is because you link to http:// which wont work as embeds now have to be over SSL. It seems that your site does work over HTTPS though, it just doesn’t redirect users automatically. If you go directly to https://www.cretinhop.net/cretintv the embed works fine.
