Variation Image not swapping

HI guys.

I have a site that has landed on my lap, I wasn’t the one that created it but I can figure most things out, however I can’t seem to find the problem why when selecting a variation the image does not change. I have changed the theme to twentytwenty to test and it works fine there. If anyone can help I would be very grateful. I will post any files/ links that you ask for as I just don’t want to start dumping a load of potentially irrelevant files right of the bat.

thanks
