Prefooter widgets problem

Hi Alex,

First of all thank you for sharing this great theme.

I am not sure I do something wrong but I am having a problem with the widgets layout in the Prefooter section.
In Corpo 1.3.1 or 1.3 the Prefooter section widgets only showed vertically and not horizontally.
They showed very nicely in Corpo 1.2. next to each other.
I tried to use 3 or 4 widgets.
Is it a bug or some setting need to be changed?

Many thanks
Fabian
