The theme uses a custom search form in the header that works slightly different from the Woocommerce search widget.
Recently, after Woocommerce update and Clickboom theme update, the new added products don't show in the search results, when using the custom search.

If I use the woocommerce search widget the products are showing just fine,

Hello, I'm a bit confused. The search function I'm talking about is theme related, is not the native wordpress function.
Basically I have a problem with the theme search function.
Or you are saying that the whole WP support, including theme related, is now moved to support.ytcvn.com ?
