On Chrome and Safari, it looks like the Jquery CDN is not loading because of an invalid certificate… To double check, It looks like the same thing is happening on the main Roots site. Does this happen for others? (just to make sure its not just my computer…) See Screenshot:
Well I run chrome regular and chrome dev versions so I just checked that exact link on chrome version 53.0.2785.143 (64-bit) and also 55.0.2883.9 dev (64-bit)
Both came back good.
Also checked jQuery 2.1.0 and both browsers are good.
