Custom and Testimonial Sliders not Loading

Hi

I have got testimonial and custom sliders working on my test site.

On the site we are rebuilding, when I put the page content in, straight from the test site the testimonial and custom sliders are not loading.

The main difference between the sites is that I haven’t imported the demo data.

Is this the issue? Am I missing something that I need that isn’t included in the theme and plugins?

Can I get these working without importing all the demo data?

There is a console error, not sure if it is relevant:

Uncaught SyntaxError: Unexpected token

<p> <!– Custom Slider –><br/>
<script type=”text/javascript”></p>
<p> jQuery(document).ready(function($) { </p>
<p> var slider_el = $(“#custom_slides_5918″);
var active_class = ” active “;
// Create Custom Icons Nav
slider_el.on(“initialized.owl.carousel”, function(e) {</p>
