With WC 3.0 they removed the support of gallery/popup/lightbox on WooCommerce product page.
To Add support for gallery/popup/lightbox on WooCommerce product pages, please try to add following code lines to theme’s functions.php file:
add_theme_support( 'wc-product-gallery-zoom' );
add_theme_support( 'wc-product-gallery-lightbox' );
add_theme_support( 'wc-product-gallery-slider' );
Filter to show only “featured” products, compatible with WC 3+.

As of WC 3, Featured Products are managed a bit differently. Before, we could use the hidden field “_featured” to filter a View. Now the flag has been migrated to a hidden taxonomy “product_visibility” and has a term name “featured”. Until this is supported in the Views GUI, a filter can be used to add the “featured” product filter to a search:
/* --------------------------------------------- */
// WooCommerce 3+ featured products filter
// Only include "featured" products
add_filter( 'wpv_filter_query', 'featured_products',99,3 );
function featured_products( $query_args,$views_settings, $view_id) {
if ($view_id == 10){
$query_args = array(
'post_type' => 'product',
'tax_query' => array(
array(
'taxonomy' => 'product_visibility',
'field' => 'name',
'terms' => 'featured',
'operator' => 'IN'
),
),
);
}
return $query_args;
}
Be sure to change $view_id == 10 to match your View.
