qoute from the theme’s demo footer:
About the Footer
The adjustable footer layout contains 8 widget areas!
Just drag and drop widgets and plugins into these sections. Don’t need this area? Simply do not add any widgets and the theme will automatically hide it for you.
the footer of your theme is totally build with using widgets
dashboard – appearance – widgets -> drag some textwidgets or other widgets into the footer widget areas…
(btw: this has nothing to so with wp_footer()
which is just a hook to hook additional functionalty to wordpress site)
