Answer 1

Cause:

Here's jquery 3 release note: https://blog.jquery.com/2016/06/09/jquery-3-0-final-released/

Removed deprecated event aliases (https://github.com/jquery/jquery/issues/2286)

• .load, .unload, and .error, deprecated since jQuery 1.8, are no more.
• Use .on() to register listeners.

Solution:

Search your custom/third-party modules code and replace the following deprecated excerpt:

$(window).load(function(){...});

with the following:

$(window).on('load', function(){ ...});
