Clicking thumbnails on product page no longer opens larger image

[loginid]

Hiya,

Thanks for making this module.

I've installed it and now when I go to a product page and click the small thumbnail images under the title: MORE VIEWS, that image clicked doesn't open into the large product image any more.

When I remove the extension the functionality works again.

I'm running Magento 1.9.3.10 on PHP 7.2

Thank you.

In a default Magento 1.9, this works without issues. I don't know how to proceed.
