Add new Widget Areas
Note: After you've added new widget areas, you'll need to reload a front end page 1-2 times before they get created and start appearing on the front end. And you'll need to reload WP->Presentation->Widgets 1-2 times before you can see the new widget areas there and start adding widgets.
is when I've selected the 'Add new WIDGET AREAS' option
