Simple wordpress task. My slider is not showing on my site.

I would like to fix my slider on my wordpress site. Just stopped working recently after some app updates broke site. I got it back up, but the slider is not coming up. I would like to also migrate site design over to shopify. I manage a shopify agency and hundreds of clients I serve monthly and if you do a good job for me on this task, and if you know how to code on Shopify I will bring you on to the development team for our shopify clients.
