cscart 2.2.4 and previewer.js

Hello, I know the version is a bit old but 'Access to this upgrade and to all future upgrades is closed. You can purchase an upgrade subscription plan at "]Customer Help Desk' ??



Anyway, I am having issues with any kind of lightbox used, either fancybox, lightbox or prettyphoto. From what I see in the fles a file name previewer.js is not loaded, so lightbox is not working at all.



I saw another thread with a similar issue but no answer is provided in it.



Anyone?
