Easy fancybox stopped working in chrome, works in IE and firefox

For now I used this code to skip fancybox on mobile and firefox but why the hell is it no longer working and does it not work on mobile at all? I came across some google finds where ppl mention fancybox on a mobile……… and they wanted it ‘disabled’ but in my case it just showed the image and clicking did nothing. The stupid thing is this started happening now with chrome too… why? There wasn’t even a plugin update?

I tried the dev version and the dev version doesn’t even load anything. It doesn’t work in any browser for me…

This is the code for the post:

<div id="mobileonly" align="center"><iframe src="https://www.youtube.com/embed/pbK2VtL02J8?wmode=transparent" height="315" width="560" allowfullscreen="" frameborder="0"></iframe><iframe src="https://www.youtube.com/embed/riyrtpEun9A?wmode=transparent" height="315" width="560" allowfullscreen="" frameborder="0"></iframe></div>

Is there anything I can do to debug and find out how or why it’s failing?

I am enquing google’s CDN jquery 1.8.3 min and jquery-ui 1.8.21 min

I gave up on this plugin, switched to jquery colorbox. Lightweight, much more customizable (via themes and css), much more friendly right out of the box, works on all browsers… still doesn’t work on mobile and i hope my php and div based desktoponly mobileonly html solution helps someone.
