I embedded a youtube video on my page, it works but it's not possible to open it FULLSCREEN. I tried everything, updated flash etc.
So where is the mistake? If i go to "embedded Media" i entered the youtube link, in source i entered the embed code which includes allowfullscreen: <iframe width="560" height="315" src="https://www.youtube.com/embed/yHkHFmeKGhI" frameborder="0" allowfullscreen></iframe>
But as soon as i save it the allowfullscreen is gone and the code transformed itself to that one on the picture below! It's nuts, please help me!
Have you tried just copying the embed HTML provided by YouTube directly into the cms static block/page. If you paste it directly into the HTML rather than use the embed media button, you might have better luck.
