Popup modal not working suddenly?

Hi,
on my site ( http://www.gg.mk/ ) the popup that comes out suddenly stopped working with youtube videos. It shows plain website like google.com but when I put url from a youtube video it does not work. Can you please see why is that happening?

Thanks,

Could you make your site online ? Now without login and password it is impossible to check anything.

Hi,
it is up. Please lets do this fast cause we need to make it public today ;D

Click the arrow (Погледнете го GG - тизер в.0.5).

Thanks,

Hi,
I just tried third party addon from JCE and its the same. Its like my Joomla don't allow playback of videos.
Where should I search the problem?

Still no one to check and tell me the solution?

I fixed this.
The problem was that I entered the URL from the address bar in the source. Instead of this I needed to get the url from the embed frame window.

Thanks,
