WPyogi on "[Theme: Landscape] Can't add widgets to footer"

If the theme doesn't have widgets in the footer, you can add them :

Any changes like that should be done in a Child Theme - see:

http://codex.wordpress.org/Child_Themes

Or, depending on what you want to do, you could just modify the footer.php file to add what you want - again, do so in a Child Theme.
