Hey KF,
in Kanso, like in most other WordPress themes, the footer is a widget area which can be populated by widgets; could you please try updating the theme with this file (unzip the archive and upload the contained file into the theme folder: /wp-content/themes/Kanso), refresh the website and then check the “Appearance -> Widgets” admin section – is there a “Footer” widget area available for adding widgets? Thanks!
Sincerely,
Andrii / Satori Studio
