The slider is not working when I installed it in my web site. I see that in your demo the slider is working. When I compared the code of your demo, the following line that exists in your demo does not appear in my web site:
<script type=’text/javascript’ src=’https://gracethemes.com/demo/powerclub/wp-content/themes/powerclub/js/custom-animation.js?ver=4.7.10′></script>
It looks like the version I purchased is not the same as what’s in the demo.
One more thing. When I use Inspect in Chrome, I see that in both your demo and in my own site a lot of 404 errors are shown in the console.
Please have the problems fixed. Thanks!
