Mengubah lebar box pada os commerce 2.3.1

Buka file includes/classes/osc_templates.php

class oscTemplate {
var $_title;
var $_blocks = array();
var $_grid_container_width = 24;
var $_grid_content_width = 16;
var $_grid_column_width = 4;

Ubah nilai $_grid_column_width sesuai keinginan, dengan syarat ($_grid_column_width x 2) + $_grid_content_width = 24.
Maka kedua column box akan berubah ukurannya.
