Uncaught TypeError: Cannot read property ‘instance’ of undefined

I’m getting an error from FTS that seems to be interfering with other .js on my site. The error is below:
Uncaught TypeError: Cannot read property ‘instance’ of undefined
at HTMLDocument.<anonymous> (magnific-popup.js:5)
at i (jquery.js:2)
at Object.fireWith [as resolveWith] (jquery.js:2)
at Function.ready (jquery.js:2)

The linked files are here:
(magnific-popup.js:5)
(jquery.js:2)

Any idea what this is or how to fix it?
