embedded youtube video keeps disappearing
I have just published my first ad. I tried to embed a youtube video in the description box (after opening the html screen)
I added following code (that is provided this way by Youtube)
<iframe width="560" height="315" src="http://www.youtube.com/embed/BmqBL--B5CE?rel=0" frameborder="0" allowfullscreen></iframe>
In the preview I see the video embedded, but when saving and watching my ad on www.eshops.be
I see it has disappeared.
Does someone know what the problem is?
