product extra fields

[Guest]

Hallo, I installed Product Extra Fields Contribution, I can create a new extra field and I see it in the "insert product page" and "edit product page".

I can write a value in each extra field and see it in the preview page of the product...

BUT I don't get any extra field in the product page of my catalog and if I edit the product I see that the extra field is empty.

I checked the db and in fact I have no value stored in the "products_to_products_extra_fields" table, which remains empty.

It looks like it doesn't write on the db... What's the problem?

The rest works fine, I can add products, manufacturers etc.

 

Thanks for your help.
