HP Slides not loading after update

Hi

I’m running the office theme and for some reason after updating wordpress, the slides will not load. In the place where they usually display on the homepage is just a loading bar that never completes.

Testimonials in the bottom centre widget space will also not load.

Any assistance or suggestions to combat this is greatly appreciated.
Thank you
