Problem using the plugin

I’ve added the plugin using the following line in my homepage but it won’t show the slides due to an error saying “wppsac-public.js?ver=2.2.3:11 Uncaught TypeError: Cannot read property ‘dots’ of null”.

Line used to add the shortcode:

<?php echo do_shortcode( ‘[recent_post_slider limit=”4″ design=”design-3″ dots=”false”]’ ); ?>

If there’s any difference I’m using a child theme.

I’ve hidden the plugin now, but the code is still on the page, and you can find it inspecting the code.

The page I need help with: [log in to see the link]
