Hello,
Add the below code to child theme functions.php to display tags
add_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_product_loop_tags', 5 );
function woocommerce_product_loop_tags() {
global $post, $product;
$tag_count = sizeof( get_the_terms( $post->ID, 'product_tag' ) );
echo $product->get_tags( ', ', '<span class="tagged_as">' . _n( 'Tag:', 'Tags:', $tag_count, 'woocommerce' ) . ' ', '.</span>' );
}
Regards
