no informations on product page

[madapet]

Hello,
I made my first prestashop site and I lost some data
In product page I cannot see the short description or the "more info" tab, for none of my 20 products, in different categories.
If I add a new product, these informations are also missing in the Front Page.
In Administrator Panel, I can see all informations for all products
I have PrestaShop 1.3.7. and I use Prestashop theme.
Is there any option for admin to show or not these informations?
Is this a module that I could accidentally broke?

Thank you

Fixed:
I change language, and only for one I have the details !
Bye
