Hello. Please tell me, why do not appear the normal WordPress post page with the goods, if the open category has no products? I'm just bringing goods on stock, at least his hands, though using shortcode, when I turn on the category page, I have no posts benefits, for example. Or slider reviews.
He realized his mistake. The website was done a long time ago, very little knowledge was deduced data via if ( have_posts() ). But in the empty category, the posts is in fact not.
