Can’t see product details on order view in status completed

Hello,

i figured out a strange problem:

I make an order, when it is onhold i see all normal, but if i update the order to completed i can’t see the product details, neither on the admin, neither on the front end account, neither in the pdf invoice.

Did anyone figured out with this ?

I am putting online for some hours in order you to see it, because i have it in maintainance mode.

Thank you

Mirko
