Add comments to portfolio items

Hi there!

I am trying to add comments to simple portfolio items, so I replaced

get_template_part( 'includes/loop', 'portfolio-single' );

with

get_template_part( 'includes/loop', 'portfolio-single' );

                        //wordpress function that loads the comments template "comments.php"
                        comments_template( '/includes/comments.php');

in single-portfolio.php as you suggested in another thread.

Am I doing something wrong? No luck so far… By the way, Im using Enfold Photography Portfolio demo, don´t know if that may have something to do.

Thanks!
