Cumulus Support

But no error message just after the line "Updating station settings"?

What locale are you using and what version of mono?

Mono JIT compiler version 3.2.8 (Debian 3.2.8+dfsg-10)
Loc. Ita/Italian
No further errors

That version of mono doesn't work with locales which use commas for decimal separators, as mentioned at the start of the MX FAQ post.

Ok, but why I have an error only on the first label of the web page? Just to know

You have other errors too, as in the screen shot you posted. It happens whenever a floating point (decimal) number is involved.

Yes, I have errors on logs, but I can save on the configuration file when I change the other labels of Settings menu. I mean, I can change the wunderground setup, click on save and have a "Saved" pop-up. And yes, the file is correctly saved, this error appears only on the first label, that drive me crazy

Those screens don't involve decimal numbers. Whether it drives you crazy or not, the important fact is that mono 3.2.8 does not work properly with decimal commas, and hence neither can Cumulus. The FAQ says so, in large red letters. It doesn't matter that you can't use the station settings screen.

Hi,

I switch raspbian to default locales en-GB and problem was solved !

Thank you for your help.

It seems that for some reason, the -lang setting does not completely override the system default.
