Product Page on Woocommerce doesn’t appear full width

Replies: 0

Any page on my website keeps in full width if a I set this up onde the page config. Like this one: http://www.blackerlotus.com.br/contato/ Note: This page has no left or right menus.
But on the store page, even setting the page for no sidebars, the sidebars keeps showing up: http://www.blackerlotus.com.br/loja/
Is there any other config that can be made to fix this?
Thanks.
