How do I change the widget area for a page content on the Footer area just as one person did on a page of mine?
With the page instead widget:
http://www.domussapiens.com.br
Without:
http://www.domussapiens.com.br/v2
Hey Guilherme!
You can edit a page and to display or not to display footer on that page in Layout section http://i.imgur.com/klZfX5U.jpg
Then you can go to Appearance > Widgets and add needed widgets to footer column widget areas
