Refused to display 'https://www.youtube.com/watch?v=xxxxxxxxxxx&feature=youtu.be' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
A possible cause for this may be the fact that you are using the short URL of the Youtube video. A short URL looks like http://youtu.be/xxxxxxxxxxx.
Instead, you should use the full URL which would look similar to https://www.youtube.com/watch?v=xxxxxxxxxxx.
If, after this, the error persists, please, contact us by opening a ticket.
