Products filter

Hi dez82,
If you paid for it why don’t you contact the developer?

The problem is with the pre_get_post filter in functions.php. It should look like this:

add_filter( 'pre_get_posts', 'bavotasan_search' );
/**
 * This function modifies the main WordPress query to include an array of
 * post types instead of the default 'post' post type.
 *
 * @param object $query  The original query.
 * @return object $query The amended query.
 */
function bavotasan_search( $query ) {
	if ( ! is_admin() && $query->is_search && $query->is_main_query() )
		$query->set( 'post_type', array( 'post' ) );

    return $query;
}

Gonna put a fix out in the next release.
