Inline gallery with zoom effect not working

[sapeish]

Hi, I have installed

Contao version 2.11.11
Isotope version 1.4.1

but i cant get the zoom effect to work, i did the following:

1. Store Configuration > Images > Product Image gallery: i selected "Inline gallery with zoom effect"
2. Product types > Product Attributes > Media management: Image gallery is selected (preselected actuallly)
3. On my reader page I placed a Module of type "Isotope E-Commerce - Product reader"

The page shows the product with all its attributes including the Image gallery but the zoom effect doesn show anywhere.

Is there something I am missing?
Is there a demo with this working somewhere? ( on http://demo.isotopeecommerce.com the zoom effect is not configured, I think it hast an older version that does not have the zoom effect yet)

Make sure you included mootools, the scripts won't run without. Then use any js console to see if errors occur. Unfortunately it is so that if any line fails all other JS will not be executed. So it may be something completely different. But you have to check your settings and then debug with a console. (I use web developer toolbar in FF for that)
