Comments Form in single post

Good day all.. I have a site https://shippingandfreightresource.com.. When there is a new post, i cannot see the comments form at the bottom.. The comments and discussion in edit options in Visual Editor is ticked..

On posts with comments like this (https://shippingandfreightresource.com/what-are-the-biggest-problems-with-container-shipments/) the comments form is showing up, but on posts without comments like this (https://shippingandfreightresource.com/beyond-brexit/) the comments form doesn’t show up..

From the theme it appears that only if there is at least one comment the form will show up (unless i am reading it wrong) but if there is no form then readers can’t comment.. Also, this used to work fine, but all of a sudden this issue is happening.. Any help will be appreciated..

Code in single.php is as below :

<?php
// If comments are open or we have at least one comment, load up the comment template
if ( comments_open() || ‘0’ != get_comments_number() )
comments_template();
?>

Code in comments.php is as below :

<?php
/**
* The template for displaying Comments.
*
* The area of the page that contains both current comments
* and the comment form. The actual display of comments is
* handled by a callback to expound_comment() which is
* located in the inc/template-tags.php file.
*
* @package Expound
*/

/*
* If the current post is protected by a password and
* the visitor has not yet entered the password we will
* return early without loading the comments.
*/
if ( post_password_required() )
return;
?>

<div id=”comments” class=”comments-area”>

<?php // You can start editing here — including this comment! ?>

<?php if ( have_comments() ) : ?>
<h2 class=”comments-title”>

<?php
printf( _nx( ‘One thought on “%2$s”’, ‘%1$s thoughts on “%2$s”’, get_comments_number(), ‘comments title’, ‘expound’ ),
number_format_i18n( get_comments_number() ), ‘<span>’ . get_the_title() . ‘</span>’ );
?>
</h2>

<?php comment_form(); ?>

<?php if ( get_comment_pages_count() > 0 && get_option( ‘page_comments’ ) ) : // are there comments to navigate through ?>
<nav id=”comment-nav-above” class=”navigation-comment” role=”navigation”>
<h1 class=”screen-reader-text”><?php _e( ‘Comment navigation’, ‘expound’ ); ?></h1>
<div class=”nav-previous”><?php previous_comments_link( __( ‘← Older Comments’, ‘expound’ ) ); ?></div>
<div class=”nav-next”><?php next_comments_link( __( ‘Newer Comments →’, ‘expound’ ) ); ?></div>
</nav><!– #comment-nav-before –>
<?php endif; // check for comment navigation ?>

<?php
/* Loop through and list the comments. Tell wp_list_comments()
* to use expound_comment() to format the comments.
* If you want to overload this in a child theme then you can
* define expound_comment() and that will be used instead.
* See expound_comment() in inc/template-tags.php for more.
