Logged-in users see my eshop differently

[lipo83]

Hello, I created my Eshop and buyed a template that supports the last versions of Prestashop (so I don't think it's a template problem).

This is my website: http://www.commetoi.it/eshop

It works fine at first sight, the problem is when you create an account and continue visiting the website you don't have permission to see the dropdown menu and access to the categories

 

For example: http://www.commetoi.it/eshop/index.php?id_product=211113&controller=product&id_lang=1

If you are logged in and try to click on the POCHETTE or BORSE category UNDER the black menu it says you don't have the permission to see those categories, but if you log out you will see them!

I didn't unchecked anything from Prestashop options or anything like that

 

Can you help me? Thanks!
