Problem with language

Hi,
I solved about menù installation (by setting position MJpanel and making new menù for mobile) but if I put the language module active for MJ I see the flags (ita and eng) but when I click on this it doesn't change language, remain always on eng. Ho can I solve this other little problem?
many tnx in advance
