FB Editor: problem connection

[Domoticatorino]

Hi,
I have updated LM to the last firmware. After the installation of FBEditor2.0 app I receive this error when I try to open it.

Error in /www/apps/data/fbeditor20/index.lp at line 11: json.encode expects at most 1 argument

What is wrong?

Thanks.
