WooCommece - Exclude a category from shop page

functions.php

<?php
/**
 * This code should be added to functions.php of your theme
 **/
add_filter( 'parse_query', 'custom_parse_query' );

function custom_parse_query( $q ) {

	if ( !$q->is_post_type_archive() ) return;

	$q->set( 'tax_query', array(array(
		'taxonomy' => 'product_cat',
		'field' => 'slug',
		'terms' => array( 'tshirts' ),
		'operator' => 'NOT IN'
	)));

	remove_filter( 'parse_query', 'custom_parse_query' );

}
?>

This does work, but when I use the Product Category Shortocde [product_category category="test-category-name" per_page="9" columns="3" orderby="date" order="desc"]

The Products from the specified category do NOT list, instead products from another category display, without pagination ..

Any ideas?

thank you

could anyone pretty please see about getting this to work again, since last update this code no longer works. .i still see all categories on the home/shop page
