Blank page after replying to a comment in Wordpress - php

Question

I'm building a Wordpress theme of my own, and having a problem with my comment-page. I can post comments, but when I press the reply-button to reply to my own comment, I get a blank wp-comments-post.php - page when posting my reply. I've tried some solutions, but it's still not working. Any ideas?
This is my comments.php file :
<?php
/**
* The template for displaying Comments.
*
* The area of the page that contains comments and the comment form.
*
*/
/*
* 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 (!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">Det här inlägget är lösenordsskyddat. Knappa in lösenordet för att se inlägget.</p>
<?php
return;
}
?>
<div id="commentsbox" class="post">
<?php if (have_comments()) : ?>
<h3 id="comments">
<?php comments_number('Inga kommentarer',
'En kommentar',
'% kommentarer'); ?>
än så länge.</h3>
<ol class="commentlist">
<?php wp_list_comments(array(
'avatar_size' => 70)); ?>
</ol>
<div class="comment-nav">
<div class="alignleft">
<?php previous_comments_link() ?>
</div>
<div class="alignright">
<?php next_comments_link() ?>
</div>
</div>
<?php else : ?>
<?php if (comments_open()) : ?>
<?php else : ?>
<p class="nocomments">Kommentarer är avstängda</p>
<?php endif; ?>
<?php endif; ?>
<?php if (comments_open()) : ?>
<div class="commentform_wrapper">
<div class="post-info">
</div>
<div id="comment-form">
<?php $comment_args = array( 'title_reply'=>'Vänligen lämna dina synpunkter och kommentarer:',
'title_reply_to' => __( 'Svara %s' ),
'cancel_reply_link' => __( 'Stäng svar' ),
'label_submit'=>'Skicka',
'reply_text' => 'Svara',
'fields' => apply_filters( 'comment_form_default_fields', array(
'author' => '<p class="comment-form-author">' . '<label for="author">' . __( 'Namn' ) . '</label> ' . ( $req ? '<span>*</span>' : '' ) .
'<input id="author" name="author" type="text" value="' . esc_attr( $commenter['comment_author'] ) . '" size="30"' . $aria_req . ' /></p>',
'email' => '<p class="comment-form-email">' .
'<label for="email">' . __( 'Mejl' ) . '</label> ' .
( $req ? '<span>*</span>' : '' ) .
'<input id="email" name="email" type="text" value="' . esc_attr( $commenter['comment_author_email'] ) . '" size="30"' . $aria_req . ' />'.'</p>',
'url' => '' ) ),
'comment_field' => '<p>' .
'<label for="comment">' . __( 'Kommentarer' ) . '</label>' .
'<textarea id="comment" name="comment" cols="45" rows="8" aria-required="true"></textarea>' .
'</p>',
'comment_notes_after' => '',
);
comment_form($comment_args); ?>
</div>
</div>
<?php endif; ?>
</div>
And this is my single.php file, in case you need it:
<?php
/**
* The Template for displaying all single posts.
*/
get_header('header3'); ?>
<section id="headerbox">
<header>
<h2 class="referensrubrik">Rubrik</h2>
</header>
<p class="referenstext">Text</p>
</section>
<?php
$post = $wp_query->post;
while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<article id="blogpost2" id="post-<?php get_the_ID(); ?>" <?php post_class(); ?>>
<h2><?php the_title(); ?></h2>
<h5><?php the_time('F jS, Y') ?> <!-- by <?php the_author() ?> --></h5>
<?php the_content(); ?>
<hr>
</article>
<?php endwhile; ?>
<?php if ($paged > 1) { ?>
<nav id="nav-posts">
<div class="prev"><?php next_posts_link('« Äldre inlägg'); ?></div>
<div class="next"><?php previous_posts_link('Nyare inlägg »'); ?></div>
</nav>
<?php } else { ?>
<nav id="nav-posts">
<div class="prev"><?php next_posts_link('« Äldre inlägg'); ?></div>
</nav>
<?php } ?>
<?php wp_reset_postdata(); ?>
<!--Start Comment box-->
<?php comments_template(); ?>
<!--End Comment box-->
<?php get_footer(); ?>

Answer 1

Most of the time this is an (500) error:
Enable debugging (see https://codex.wordpress.org/Debugging_in_WordPress)
Open your develop bar in your browser
Record the requests
Check the http status code and error info

Answer 2

This typically only happens to me when I make a mistake with either leaving a line break or space in front of the pages opening PHP tag. While it does not looks not be the case based on the example code - but I would triple check that you have no carriage returns or spaces before the opening

Answer 3

Problem solved! Because I could comment and reply comments when logged in as admin, but not as an anonymous visitor, I cheched my discussion settings. They were set to send me an email every time someone posted a comment. Somehow this is failing and when I uncheched the box the problem was gone. I need to look up why the email is failing, but for now I'm just happy that everything is working as it should.

Answer 4

Some of this problem are from the server where you are hosted, you may me able to change it on the php settings,
post_max_size
, and the
upload_max_filesize
this will the solution of many problem uploading files on wordpress
