Please Help. Woocommerce search result page issue.

Hello, the last two days I’m trying to solve a problem with a product search result. I’ve disabled all the plugins, tried different theme and clean the cache but the issue is still there. Every time I’m trying to search for any product, its shows a homepage instead of a search result page. I’m using a Kallyas theme which has a two search options: Default WordPress (blog type) search result which is working fine but the products are having an author details and no prices and WooCommerce Product Search Result which is not working at all even when a different theme is chosen.
SEARCH.PHP

<?php if(! defined('ABSPATH')){ return; }

/**
 * This is the template layout for search results page.
 *
 * @package  Kallyas
 * @author   Team Hogash
 */

wp_enqueue_style( 'search-css', THEME_BASE_URI . '/css/pages/search.css', array('kallyas-styles'), ZN_FW_VERSION );

get_header();

/*** USE THE NEW HEADER FUNCTION **/
global $wp_query;
if ( !empty( $wp_query->found_posts ) ) {
	$title = $wp_query->found_posts . " " . __( 'search results for:', 'zn_framework' ) . " " .
			 esc_attr( get_search_query() );
}
else {
	if ( !empty( $_GET['s'] ) ) {
		$title = __( 'Search results for:', 'zn_framework' ) . " " . esc_attr( get_search_query() );
	}
	else {
		$title = __( 'To search the site please enter a valid term', 'zn_framework' );
	}
}
WpkPageHelper::zn_get_subheader( array( 'title' => $title, 'title_tag' => 'h1' ) );

// Check to see if the page has a sidebar or not
$main_class = zn_get_sidebar_class( 'blog_sidebar' );
