Hey Maurizio,
first of all, thank you for the purchase!
I will go over the questions in the same order:
1). Please tell me if you’ve installed the “Contact Form Generator” plugin that was packaged with the theme? Could you please try inserting a form into one of the pages so that I could look at the code? Thanks!
2). Yes, it is indeed a bug – please accept my apologies for any inconvenience and thank you for reporting! I’ve prepared a fix, which you can download here. Please download the archive, unzip it, and upload the contained file into the theme folder (/wp-content/themes/Kanso/), replacing the existing file. The menu links outside the one-page template should work like in the theme demo now.
3). Could you please clarify what you mean by “command” in this case?
Sincerely,
Andrii / Satori Studio
