The problem is that it is not loading the Owl Carousel JavaScript and CSS files. When I view source on that page I’m not seeing these files. Should be seeing these files when you view source:
<link rel='stylesheet' id='owl_carousel_css-css' href='https://edgewebpages.com/wp-content/plugins/slide-anything/owl-carousel/owl.carousel.css?ver=2.2.1' type='text/css' media='all' />
<link rel='stylesheet' id='owl_theme_css-css' href='https://edgewebpages.com/wp-content/plugins/slide-anything/owl-carousel/sa-owl-theme.css?ver=2.0' type='text/css' media='all' />
<link rel='stylesheet' id='owl_animate_css-css' href='https://edgewebpages.com/wp-content/plugins/slide-anything/owl-carousel/animate.min.css?ver=2.0' type='text/css' media='all' />
<script type='text/javascript' src='https://edgewebpages.com/wp-content/plugins/slide-anything/owl-carousel/owl.carousel.min.js?ver=2.2.1'></script>
Because the Owl Carousel JavaScript is missing it is not initialising the slider.
Somebody else has raise a similar issue and I’m a bit stumped.
Does your theme have a ‘footer.php’ file? (look in ‘Appearance->Editor’)
What happens when you activate another theme as a test? What theme are you using?
