Website Template - Yummy; JScript errors

Hallo,
I’ve purchased this Yummy template in late December 2019.

Lately, however, certain things don’t work when using a template, … if I look in firefox & Tools & Console - i see that there are errors in the use of javascript

the Yummy template contains the following statements concerning JS:

<script src="js/jquery/jquery-2.2.4.min.js"></script>
<!-- Popper js -->
<script src="js/bootstrap/popper.min.js"></script>
<!-- Bootstrap-4 js -->
<script src="js/bootstrap/bootstrap.min.js"></script>
<!-- All Plugins JS -->
<script src="js/others/plugins.js"></script>
<!-- Active JS -->
<script src="js/active.js"></script>

how can i update this JS to make the thing work normally again

thanks,
J from Slovenia
