I am fairly new to WP, so I apologize for this very basic question, but I am working on a site that has an older version of jQuery showing up.
Here is the jQuery reference I have placed in the header, which appears on line 20 of the source code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
But on line 39 of the source code I see the following:
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js?ver=3.8.1'></script>
I have searched the files and I cannot see where this reference is coming from. I need to get rid of it and could therefore use some guidance on tracking it down. Thanks.
header.php
for the file, Found it? 'No' -> checkfunctions.php
and look for anenquque_script
function. Found it? 'No' -> try disabling all your plugins. These are the 3 things I would check.
