Counter parallax image won't load when not logged in to admin page

On the site I am working on (www.vocasolutions.co.uk) the image with the parallax effect in the counter section is completely refusing to load when not logged in to the admin panel, is there any help you can offer with this error?

Hello there,

I hope you are having a good day.

I checked the website and the parallax effect in the counter section of the page seems to work.

I managed to fix it myself actually, after trying to find a solution for the past couple of days including uninstalling and reinstalling the theme, I don’t know exactly what I did but I did something and it is working again now.
