Hello.
i have insalled woocommerce brands plugin and it work fine.
but i have a problem in the page http://new.l2gshop.com/brand/catalogo-cattelan-italia becasue work on 2 column.
(<div class="post-549 product type-product status-publish has-post-thumbnail <strong>hb-woo-product col-6</strong> hb-animate-element top-to-bottom taxable shipping-taxable purchasable product-type-simple product-cat-complementi product-tag-credenza instock hb-in-viewport">

instead 4 column of http://new.l2gshop.com/tag/divano
or

<div class="post-898 product type-product status-publish has-post-thumbnail hb-woo-product col-4 hb-animate-element top-to-bottom taxable shipping-taxable purchasable product-type-simple product-cat-zona-giorno product-tag-divano instock hb-in-viewport">

I have checked and the plugin call

<?php
/**
