Problem:
The client can't translate the strings Redes and Endereço, which appear in the site footer.

Solution:
The footer widget titles "Redes" and "Endereço" are not translatable. To make the strings translatable, the following conditions have to be met:

- The text must be wrapped in gettext calls
- There must be a textdomain argument

So instead of adding the title like this:

<h3>Redes</h3>

You could use a code like this one:

<h3><?php __( 'Redes', 'your-theme-domain' ); ?></h3>
