Youtube video in picture-video grid does not work

1

Hello everyone.

I have built an image/video grid into my website www.dellacomafanclub.com and linked a Youtube video to it.

If you want to open it, it does not appear in full size but quite small. Where can I set it to be displayed much larger? Filling the lightbox does not bring any change.

This appears to be some sort of bug affecting YouTube videos. Self hosted videos work just fine and open full size in a lightbox. Not sure if it’s a Sitely issue or a Youtube-specific issue. Maybe worth dropping a quick email to support for advice.

Maybe you know this already, but the video isn’t playing on my desktop iMac (Intel OS 15.7.7).

Thank you! No, I didn’t know that.

But there is a much more bigger problem - there is no menu in the header and I do not know why??!!
