error when viewing old products, but new ones can be seen

[sanchiago]

There is an error in the display of the products because those that were cannot be seen, it only shows the navigation, but if I add new products, they can be seen as they should be.

There they are displayed displayed but should be seen in a single box, and the others go by with the navigation.

here the product is shown well, this is a new product added recently.

New install,  upgrade ?

You have a lot of jscript errors. Some of them regarding fancy box that is used to display the images.

Perhaps an outdated custom template ?

Images seem to be visible with protostar.

It is a template / JS problem

on https://vmruedas.com.ar/index.php/ruedas-herrajes/ruedas-simples/73/26/canal-v/ruedas-simples-canal-v-rs50-detail your  loading Jquery AFTER jquery.fancybox-1.3.4.pack.js
you are also loading it twice

on https://vmruedas.com.ar/index.php/ruedas-herrajes/puntas-metalicas-tipo-dubai/154/punta-metalica-tipo-dubai-80-detail you are loading jquery correctly before fancybox

you need to find out why...

[sanchiago]

how I can find that? or What can I do? I'M sorry but I don't have many ideas

I updated VM and now it does not show me categories or products

this is a problem with YOUR template...  so u need to ask your template supplier or employ someone to fix it...

Standard VM with a standard template .. e.g. Beez3 doesn't have these problems
