These are the only declarations I can see:
<script type=’text/javascript’ src='<website domain removed>/wp-includes/js/jquery/jquery.js?ver=1.11.1′></script>
<script type=’text/javascript’ src='<website domain removed>/wp-includes/js/jquery/jquery-migrate.min.js?ver=1.2.1′></script>
They look like the standard jQuery with WP?
