Fancybox Plus not working, how to fix or change to a new plugin?

Hi, my site https://www.drivenaudio.ca has been up for a couple years now and works well, except that when people click on pictures from my Flickr feed on my pages, they no longer pop up.

Instead a small black box pops up with a spinning wheel in it, it stays that way until the box is clicked.

I’ve tried turning other plugins on and off and I’m sure it’s a problem or conflict with FancyBox Plus plugin that does the “lightboxing” feature on my site.

From the research I’ve been doing, I’m guessing it has something to do with jQuery updates or something like that.

I’ve also noticed it plays with the Facebook stream window – sometimes it will show sometimes not.

So, I’m trying to figure out how I can determine if it’s a code thing I can fix, and if not how I can change to another more supported plugin that is still be updated.

Thanks in advance for any help you can provide… I’m slowly learning this stuff! ??
