Hello :),
Please make sure that you are including on footer of document the script:
<script src="js/examples/examples.gallery.js"></script>
Also make sure that you are including the files of plugin “Owl Carousel”:
CSS:
<link rel="stylesheet" href="vendor/owl.carousel/assets/owl.carousel.min.css">
<link rel="stylesheet" href="vendor/owl.carousel/assets/owl.theme.default.min.css">
JS:
<script src="vendor/owl.carousel/owl.carousel.min.js"></script>
If you still can’t solve the issue, please send the link of your website for us. So we can inspect your code and discover where is the problem for you.
Best Regards,
Rodrigo.
