Wordpress Search showing a blank page for empty results

[admin]

I've had to put together a custom search that sends the user to different search result pages based on which form they've filled out and the search also has been set to search custom post types.

When the search finds a result everything displays correctly but when it does an empty search it doesn't seem to be running the content-none.php template. Instead of "Sorry, but nothing matched your search terms. Please try again with some different keywords." It's just an empty page with the header and footer.

For an example you can go to: <a href="http://biozymeconnect.ev-labs.com/reseller/" rel="nofollow">http://biozymeconnect.ev-labs.com/reseller/</a> and in the second input use "tx" for a search with results and then something random for a search without results.

Details:

<ul>
<li>Base Theme: underscores </li>
<li>Framework: Foundation by Zurb</li>
</ul>

Custom Post Type search changes were made using this code <a href="http://adambalee.com/search-wordpress-by-custom-fields-without-a-plugin/" rel="nofollow">http://adambalee.com/search-wordpress-by-custom-fields-without-a-plugin/</a>

/**
 * Extend WordPress search to include custom fields

 */

/**
 * Join posts and postmeta tables
 *
 * http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_join
 */
function cf_search_join( $join ) {
    global $wpdb;

    if ( is_search() ) {    
        $join .=' LEFT JOIN '.$wpdb->postmeta. ' ON '. $wpdb->posts . '.ID = ' . $wpdb->postmeta . '.post_id ';
    }

    return $join;
}
add_filter('posts_join', 'cf_search_join' );

/**
 * Modify the search query with posts_where
 *
 * http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_where
 */
function cf_search_where( $where ) {
    global $pagenow, $wpdb;

    if ( is_search() ) {
        $where = preg_replace(
            "/\(\s*".$wpdb->posts.".post_title\s+LIKE\s*(\'[^\']+\')\s*\)/",
            "(".$wpdb->posts.".post_title LIKE $1) OR (".$wpdb->postmeta.".meta_value LIKE $1)", $where );
    }

    return $where;
}
add_filter( 'posts_where', 'cf_search_where' );

/**
 * Prevent duplicates
 *
 * http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_distinct
 */
function cf_search_distinct( $where ) {
    global $wpdb;

    if ( is_search() ) {
        return "DISTINCT";
    }

    return $where;
}
add_filter( 'posts_distinct', 'cf_search_distinct' );

To customize the search results I used this tutorial <a href="http://wpgarage.com/code-snippets/how-to-customize-multiple-search-result-pages-in-wordpress/" rel="nofollow">http://wpgarage.com/code-snippets/how-to-customize-multiple-search-result-pages-in-wordpress/</a>

edited the search.php to be

<?php
/* Template Name: Search Results */
$search_refer = $_GET["site_section"];
if ($search_refer == 'reseller') { load_template(TEMPLATEPATH . '/reseller-search.php'); }
elseif ($search_refer == 'site-search') { load_template(TEMPLATEPATH . '/dealer-search.php'); }; ?>

I edited the reseller-search.php and dealer-search.php to be.
