How to enable image zoom?

Question

CMS

Good day to all !
People, tell me what kind of garbage, the image in the product card does not zoom (it does not increase in size when clicked),
I put the default files product.tpl and product.php - it still does not work.
What could it be?
Version Opencrt 2102
in the standard assembly of this CMS everything works as expected. Tell me, can anyone come across such garbage?
PS in the admin panel everything is fine. Magiczoom modules and others installed on do not work

Answer 1

What's your build? What is the topic?
Do you put the standard product.tpl in your theme?
Most likely the modules you are installing are not compatible with your theme. See the vqmod/ocmod file from the module and make manual edits for your theme.

magnific popup is responsible for magnifying the image, and if you overwrote the files, then probably the library itself is not loaded, but at least it should throw you on a click to a new page and the image itself without a modal window.
And so there is an inspector in chrome, take a look at what is not loaded or what it swears at when clicked.
Or throw the patient here, and we will look at a live example.
