A past client’s website of mine had several $.live() triggers as that was a great way to attach triggers to future dynamically created objects using jQuery. However, and we have known that this would be coming, but $.live() has now been depreciated and removed from jQuery with the replacement being $.on(). Any past code referencing $.live() will now stop working if the jQuery library is updated past version 1.9.
An illustration below is how to convert to using $.on():
Where you previously had:
$('.button').live('click', function(){});
Now becomes:
$(document).on('click', '.button', function(){});
