Well, although I don't know Italian (I dated one once though) so I am not sure if Italian has any special characters in the text that may cause issues?
Perhaps its a database field naming issue where you named a field a reserved word or something?
Again, just throwing some ideas out there.
My suggestion would be that if it is the Italian version that is the issue, to offer the WA guys some help in the translation rather than jumping on them. I am sure Italian isn't their first language either.
Never know you might be rewarded .......
