Dont Show the Sidebar on Product Category Page

You need to remove the following lines of code from the archive-product.php

<?php
	/**
	 * woocommerce_sidebar hook
	 *
	 * @hooked woocommerce_get_sidebar - 10
	 */
	do_action('woocommerce_sidebar');
?>

or, hook the sidebar out by adding the following lines of code to your functions.php (best way to do it actually)

remove_action( 'woocommerce_sidebar', 'woocommerce_get_sidebar', 10);
