Popup and Lightbox are not appearing on our Portfolio

Hello,

My name is Sammy Barbosa and I have recently purchased the JUX Portfolio Module for our website. It is very nice. But we have encountered a problem when it comes to making the Popup and Lightbox appear on our grid layout, nothing is turning up.

Could you please give us a hand with this?

This is our stage website stagemodulos.colombobritanico.edu.co/index.php/es/ You can see that we have featured the Portfolio close to the bottom of the page. When you hover over the images on the grid, the icon hovers work fine, but when you click on the magnifying glass for the Popup, it does not work.

Any ideas on why this is happening?

Thanks
