Incompatible with jQuery 3

Does not show content if jQuery 3 is used:

Uncaught TypeError: a.indexOf is not a function
at r.fn.init.r.fn.load (jquery.min.js?ver=3.1.1:4)
at jquery_loaded (cdn.rewardsfuel.com/embed.js:7)
at cdn.rewardsfuel.com/embed.js:3
at cdn.rewardsfuel.com/embed.js:10

This stops me from purchasing a license. Would be a very useful plugin for my purposes.

Here are some useful links to fix this issue:
