1. Do you have any widgets added to the Footer 1, Footer 2, Footer 3 widget boxes? If there are no widgets, they won’t show up.
2. You have an empty widget area created in Theme Options > Sidebars. Click the red button to remove it. It may cause bugs. (I’ve added a check for this in an updated version so it won’t appear)
3. You seem to have modified the admin panel. Perhaps some small code thing has gone wrong.
