Hi all,
I downloaded a website and the slider section doesn’t work instead I get the message below;
!! Error at loading Slider Revolution 5.0 Extrensions.

Put this to your header:

<script type="text/javascript" src="//themes.lpd-themes.com/naslaan-03/wp-content/plugins/revslider/public/assets/js/extensions/revolution.extension.slideanims.min.js"></script>

<script type="text/javascript" src="//themes.lpd-themes.com/naslaan-03/wp-content/plugins/revslider/public/assets/js/extensions/revolution.extension.parallax.min.js"></script>

Please How do I correct this issue?

Welcome, @bongodc. Could you please post the link to your site so that we can see the code? You will probably get more responses from the WordPress section, so I’m going to move your thread over there.
