Problem Page product – squarespace

Hi Dave,
Multilingualizer is causing troubles in our Squarespace website. We really need your help to fix it.
Our website perfectly works when we remove the Multilingualizer code but we really need the two languages.
When we inject the Multilingualizer code, the name and the description of the product, the price and the button “Purchase” doesn’t display anymore in the product pages (in the french version) http://www.nesmontreal.com/bracelet/titre-frtitre-an-7aaan-3pncm-asa98-7kl45-hkzf8-apted-m85j2-sr25x-csbka-bjhjt-rszsj-h4efs-lsns4-7lnek.
We have already updated the Multilingualizer with the last version of the code but it still doesn’t work.
Can you fix the Multilingualizer code please?

Thanks and best regards,

Pauline
