WPCS Slider Broken

Hi there,

On https://bridgecommercials.co.uk/ I had a slider underneath "Featured Vans", but as you can see, it is not displaying.  This was working just fine up until recently.

I have no idea what has changed to cause this to happen and have looked through the slider settings etc and don't know how to get it going again.  I disabled all plugins apart from WooCommerce, this plugin and advanced custom fields (website broke with ACF disabled) and it still wasn't working, so doesn't seem to be a plugin conflict.

Any help would be much appreciated.

Thanks,
Ronan
