Volumio on touchscreen - Translation problem

Hi guys.

First of all, sorry for my bad english!

I’ve installed the touchscreen plugin and it work well.

There is however a problem: the Chromium browser, who runs in fullscreen mode, shows me every time a popup in which it offers me to translate in english the Volumio UI (I’ve setted it in italian).

So I’ve tried to access the setting page of the Chromium browser and disabled the automatic translation.

This solution works only partially, because when I restart Volumio the popup appears again: when I shutdown the system, the Chromium browser doesn’t save my preferences.

Is there a way to permanently disable the translation popup?

Thank you for your help!
