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);
}
?>

Great, pls provide a temp user pass for us with sufficient rights so we can log in and see what’s going on and edit the files further if needed! (use a private reply).

“Kommentare erlauben.” !!

I also moved the comments a bit up in the portfolio item template so they appear after the content.

Have in mind this customization may get lost at theme update so you may want to make the change of the template in your child theme.

\wp-content\plugins\fortuna_portfolio_cpt\fortuna_portfolio_cpt.php
‘supports’ => array(‘title’, ‘editor’, ‘thumbnail’, ‘comments’),
is ok.

comments are on.

but when i add:

/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);
}
?>

there is a error

Parse error: syntax error, unexpected ”off’) == ‘on’; ‘ (T_ENCAPSED_AND_WHITESPACE) in /www/htdocs/w0136f66/casida.de/wp-content/themes/fortuna/single-portfolio_empty.php on line 24

but i will add comments in the portfolio.
has anybody an idea ?
