AdSense not working correctly

I wanted to implement Google AdSense Ads to my Blog. I created the AdSense Account and created the Ads and Google gave me the HTML Code I should copy to where the Ads should appear.

Now I added, for testing purposes, the Code to this page (above the YouTube Video): http://www.davicii.com/million-mask-march-vienna-2014/

And I just see white space and some sort of code. On every device I view it, it’s like this.

And also on the sidebar widget it’s just white space, so i deactivated the widget till it works.

Can somebody help me solve this problem?

thx in advance!

ps: i already tried deactivating all plugins: does not help :/
