Reply To: Some products don't show up in the search results

Hi Erwin,

Some time ago, WooCommerce has changed the way of how the product visibility works. This method should no longer work on the most recent WooCommerce installations.

Instead of that code, can you please try the updated solution: https://wp-dreams.com/knowledge-base/woocommerce-excluding-hidden-products/

I feel that will very likely solve the problem.
