CG on homepage

Hello there,

I´m trying to get work this plugin on my website´s homepage. First od all I used do_shortcode() function in home.php. But it wasn´t working, becase it wasn´t attached to any post/page (I think).

So after that, I created page, where I put the Commnet Guestbook shortcode. And in home.php I put something like this:

<?php
 $temp = $wp_query; $wp_query= null;
 $wp_query = new WP_Query();
 $wp_query->query('pagename=zed');
	while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
	<?php the_content(); ?>
<?php endwhile; wp_reset_query(); ?>

Comment Guestbook was finally on my homepage. But! When I try to submit comment or go to second comment page I am redirected to original page with CG.

Is there any code I can put to my functions.php to get CG working on home?

Thank you for your help in advance.
