[Theme Gallery] Help with widgets

Hi!! The theme is gallery.

I am facing problens to display widgets in some widget area called “Index Top: The top widget area displayed on the index page.”

I have installed the Polylang plugin to generate a dropdown menu of idioms. Once I added to the footer, it is displayed, however at the top of page nothing is displayed.

My page is located at the following addres: http://www.felipeandres.com.br

And I want the header to be like this:
http://www.felipeandres.com.br/demo-felipeandres.jpg

Somebody help me please! thanks!
