Footer Columns Extra Class

Dear guys,

I have no clue how to separate the footer into 3 columns. I need to insert some magic code in the “extra class” box. There was one, but I accidentally deleted it and don’t know how to restore it back to the 3-column form.

The website now looks like this, you’ll easily realize what the problem is by entering my website: http://porasia.com/. The footer widgets are piled up and not in a 3 column line.

Thank you very much.

Best regards 🙂

Santiago
