Jak włączyć komentarze dla starych postów?

Cześć, mam dziwny problem jeśli chodzi o komentarze wyłączyłem kiedyś komentarze i jak teraz np.dodam nowy post to komentarze dla nowy postów są otwarte. Próbowałem w  ustawieniach wordpressa wyłączyć i włączyć komentarze jest to samo stare posty mają komentarze wyłączone a nowe włączone probowałem również kombinować z wtyczką Disable Comments, ale to samo... Wychodzi na to, że trzeba pogrzebać w pliku comments.php. Proszę o pomoc. Poniżej kod. 

<?php
 
// Do not delete these lines
if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))
die ('Please do not load this page directly. Thanks!');
 
if ( post_password_required() ) { ?>
<p class="nocomments"><?php _e('This post is password protected. Enter the password to view comments.','mythemeshop'); ?></p>
<?php
return;
}
?>
<!-- You can start editing here. -->
<?php if ( have_comments() ) : ?>
	<div id="comments">
		<div class="total-comments"><?php comments_number(__('No Responses','mythemeshop'), __('One Response','mythemeshop'),  __('% Comments','mythemeshop') );?></div>
		<ol class="commentlist">
			<div class="navigation">
				<div class="alignleft"><?php previous_comments_link() ?></div>
				<div class="alignright"><?php next_comments_link() ?></div>
			</div>
			<?php wp_list_comments('type=comment&callback=mytheme_comment'); ?>
			<div class="navigation">
				<div class="alignleft"><?php previous_comments_link() ?></div>
				<div class="alignright"><?php next_comments_link() ?></div>
			</div>
		</ol>
	</div>
<?php else : // this is displayed if there are no comments so far ?>
	<?php if ('open' == $post->comment_status) : ?>
		<!-- If comments are open, but there are no comments. -->
	<?php else : // comments are closed ?>
		<!-- If comments are closed. -->
		<p class="nocomments"></p>
	<?php endif; ?>
<?php endif; ?>

<?php if ('open' == $post->comment_status) : ?>
	<div id="commentsAdd">
		<div id="respond" class="box m-t-6">
			<?php $comments_args = array(
					'title_reply'=>'<h4><span>'.__('Leave a Reply','mythemeshop').'</span></h4></h4>',
					'comment_notes_after' => '',
					'label_submit' => __('Post Comment','mythemeshop'),
					'comment_field' => '<p class="comment-form-comment"><textarea id="comment" name="comment" placeholder="'.__('Comment','mythemeshop').'" value=" cols="45" rows="8" aria-required="true"></textarea></p>',
					'fields' => apply_filters( 'comment_form_default_fields',
						array(
						'author' => '<p class="comment-form-author">' 
							. '<label for="author">' . __( 'Name', 'mythemeshop' ) . ':<span class="required">*</span></label>' 
							. ( $req ? '' : '' ) . '<input id="author" name="author" type="text" placeholder="Name" value="' . esc_attr( $commenter['comment_author'] ) . '" size="30" /></p>',
							
						'email' => '<p class="comment-form-email"><label for="email">' . __( 'Email', 'mythemeshop' ) . ':<span class="required">*</span></label>' 
							. ( $req ? '' : '' ) . '<input id="email" name="email" type="text" placeholder="' . __( 'Email', 'mythemeshop' ) . '" value="' . esc_attr(  $commenter['comment_author_email'] ) . '" size="30" /></p>',
							
						'url' => '<p class="comment-form-url"><label for="url">' . __( 'Website ', 'mythemeshop' ) . ':</label>' . 
		'<input id="url" name="url" type="text" placeholder="' . __( 'Website ', 'mythemeshop' ) . '" value="' . esc_attr( $commenter['comment_author_url'] ) . '" size="30" /></p>' 
		
		) )
			); 
			comment_form($comments_args); ?>
		</div>
	</div>
<?php endif; // if you delete this the sky will fall on your head ?>

A sprawdź w czymś takim - przejdź do karty z wszystkimi postami i kliknij w "szybką edycję" i tam zaznacz, zezwól na komentarze... Daj znać czy pomogło
 

Kiedyś też tak miałem i przeinstalowanie WP pomogło.
