Portfolio pages with comments

Hello,
the Problem:
How can I add user comments under the Portfolio Template / Sites ?

This i did
You first need to enable comments for the custom post type internally, edit your \wp-content\plugins\fortuna_portfolio_cpt\fortuna_portfolio_cpt.php

and mod this:

‘supports’ => array(‘title’, ‘editor’, ‘thumbnail’),
to this:

‘supports’ => array(‘title’, ‘editor’, ‘thumbnail’, ‘comments’),
Then what you have left is add the code that adds the comments template to your portfolio template you are using, for example: \wp-content\themes\fortuna\single-portfolio.php

Then:
Portfolio Page Option Empty

/wp-content/themes/fortuna/single-portfolio_empty.php

<?php
/**
* Template Name Posts: Portfolio Empty Page
*/

get_header(); ?>

<div class=”container”>
<div class=”post_content section portfolio_page”>
<?php while(have_posts()): the_post(); ?>

<div id=”post-<?php the_ID(); ?>” <?php post_class(); ?>>
<?php the_content(); ?>
</div>

<?php endwhile; // END LOOP ?>
</div>
</div>

<?php get_template_part(‘includes/related_portfolio_items_inc’); ?>

<?php get_footer(); ?>
<?php
$show_page_comments = ot_get_option(‘show_page_comments’,'off’) == ‘on’;
if($show_page_comments) {
comments_template(”, true);
}
?>
