Sorry for the trouble there. I took a look and it appears that only one slide has been published at the moment. Go to the slides spot in your dashboard and make sure that more than one slide is there and published. Once you have more than one slide, the slideshow should be able to work.
I’m still only seeing one slide in the code on your front end. Could you send over a login to your site so I can take a closer look for you? You can mark the reply as private and I’ll be the only one who can see it.
