Duplicates on Authors page

I just realized I have this same problem. To boot, the authors are missing in the back end for nearly all of my posts! I cannot even find any systematic reason for why this happened. Aside from creating short codes for coauthors in some places, the only additional code I have for coauthors plus is the following:

function add_pagination_to_author_page_query_string($query_string){
	   if (isset($query_string['author_name'])) $query_string['post_type'] = array('post', 'books' , 'attachment');
	   return $query_string;
	}

This simply makes sure that coauthors attached to my custom post type, “books,” appear in author post listings.

This really sucks. Only the first author appears now on the actual post but the if there were any coauthors have, they have vanished. In addition, when I fixed one of my posts (which had no authors listed) by adding the author and coauthor, the author listing only brought up that individual post—even though I know this author has many posts, and not just custom “books” posts, which is what I edited.

One thing that I noticed is that this appears only to affect the authors of my custom posts. However, these are the only posts that have multiple authors.

Here is the various shortcut code that I use in case it might be helpful.

/* Custom shortcode */

	add_shortcode( 'mr-coauthor-link-inline', 'mr_coauthor_inline_shortcode' );
	function mr_coauthor_inline_shortcode() {
		global $post;
		$isedited = get_post_meta( $post->ID, 'Editors', true );
		$contributor = get_post_meta( $post->ID, 'Contributor', true );
  	if ( function_exists('coauthors_posts_links') && !empty( $isedited ) && !empty( $contributor ) )	{
  		coauthors_posts_links(', ', '<em>' . $contributor . '</em> ', ' <em>' . $isedited . '</em> <span class="coauthors-yarp ed-contrib">' , '</span>' );
			 	}
  	else if ( function_exists('coauthors_posts_links') && !empty( $isedited ) )	{
  		coauthors_posts_links(', ', ' and ', ' <em>' . $isedited . '</em> <span class="coauthors-yarp ed">' , '</span>' );
			 	}
	else if ( function_exists('coauthors_posts_links') && !empty( $contributor ) )	{
  		coauthors_posts_links(', ','<em>' . $contributor . '</em> ', ' <em>by</em> <span class="coauthors-yarp contrib">' , '</span>' );
			 	}
	else if ( function_exists('coauthors_posts_links') && empty( $isedited ) )	{
		coauthors_posts_links(', ', ' and ', ' <em>by</em> <span class="coauthors-yarp">' , '</span>' . $contributor );
			 	}
	else if (!function_exists('coauthors_posts_links'))	{
		the_author_posts_link();
		}
	}

	add_shortcode( 'mr-coauthor-link', '
	function mr_coauthor_shortcode() {
		global $post;
		$isedited = get_post_meta( $post->ID, 'Editors', true );
	  	$contributor = get_post_meta( $post->ID, 'Contributor', true );
  	if ( function_exists('coauthors_posts_links') && !empty( $isedited ) && !empty( $contributor ) )	{
  		coauthors_posts_links(', ', '<em>' . $contributor . '</em> ', ' <div class="byline"><em>' . $isedited . '</em> <span class="coauthors">' , '</span>' );
			 	}
  	else if ( function_exists('coauthors_posts_links') && !empty( $isedited ) )	{
  		coauthors_posts_links(', ', ' and ', ' <div class="byline"><em>' . $isedited . '</em> <span class="coauthors">' , '</span>' );
			 	}
	else if ( function_exists('coauthors_posts_links') && !empty( $contributor ) )	{
  		coauthors_posts_links(', ', '<em>' . $contributor . '</em> ', ' <div class="byline"><em>by</em> <span class="coauthors">' , '</span>' );
			 	}
	else if ( function_exists('coauthors_posts_links') && empty( $isedited ) )	{
		coauthors_posts_links(', ', ' and ', ' <div class="byline"><em>by</em> <span class="coauthors">' , '</span>' . $contributor );
			 	}
	else if (!function_exists('coauthors_posts_links'))	{
		the_author_posts_link();
		}
	}

After installing the plugin I get duplicates on my authors page.

Can you share the code used to generate the list of author posts on your site? Did you configure the site originally, or did someone else help you with it?

Aside from creating short codes for coauthors in some places, the only additional code I have for coauthors plus is the following

What is this hooked into?

In addition, when I fixed one of my posts (which had no authors listed) by adding the author and coauthor, the author listing only brought up that individual post

Have you written custom code for this author listing?

Hey Daniel,

I haven’t used any custom code to generate the list. It only duplicates the posts on the authors template page when the plugin is enabled. Like this page:

https://awakenmag.com/author/bethanyreid/

I personally didn’t configure the site. I am assisting someone in remedying the problem.

What is this hooked into?

functions.php for my theme. I’m just generating shortcodes and then altering the byline of my articles using the Hybrid theme (actually, the Prototype theme that uses the Hybrid framework. https://themehybrid.com)

Have you written custom code for this author listing?

I’m not sure what you mean, but not for this author listing in particular. I simply add the aforementioned shortcodes in the appropriate places.

Hi! I’m having the same issue- duplicate articles show up on author pages. Samuel, I notice that we are using the same theme (Gonzo), which might go a way towards explaining it. I’d love any help towards fixing the problem!

The author code is fairly complex, customized by the theme to output a special page. I’ve copied the two key files below, author.php and a second file that is called to loop.

<?php get_header(); ?>

<section id="omc-main" class="omc-main-author">	

	<?php if (!is_paged()) { ?>	

		<?php if ( get_the_author_meta( 'description' ) ) : ?>

				$twitter = get_the_author_meta( 'twitter' );
				$facebook = get_the_author_meta( 'facebook' );
				$linkedin = get_the_author_meta( 'linkedin' );
				$youtube = get_the_author_meta( 'youtube' );
				$google = get_the_author_meta( 'google' );
				$soundcloud = get_the_author_meta( 'soundcloud' );
				?>

				<span id="omc-author-page-image"><?php  echo get_avatar( get_the_author_meta( 'user_email' ), apply_filters( 'twentyten_author_bio_avatar_size', 104 ) ); ?>		</span>	

				<h1><?php printf( __( 'About %s ', 'gonzo' ), get_the_author() ); ?><?php echo $last; ?></h1>

This might be the offending piece though. It’s a file called loop-blog-style-2.

Thanks for taking the time to share your files, gregrmay. Nothing pops out right away at me :/

Sam: I notice the posts aren’t duplicated on your site anymore. Did you track it down?

Thanks for taking a look! I posted on the theme designer’s forums as well.

I believe Sam stopped using the co-authors plugin, as did I, at least until I can figure out what is causing the issue.

One additional clue: at least for me, the duplication only happens for authors who do not have enough posts to reach a second page. Authors with enough articles to be paginated do not have this issue, it seems.

Happy to play around with some code if you have any suggestions!

I don’t — sorry. It sounds like this is a theme issue.

Actually, I think I may have tracked this down based on some debugging I did this afternoon with a friend. Did you edit the user_nicename value for any of the authors that have duplicate posts by chance?

Yes, though I believe that I edited the nicename for all authors, so that doesn’t seem likely to be the only culprit?

@gregrmay I’ve detailed the problem and how you might fix it in another thread. Let’s continue the discussion there.

I feel this discussion might have become sidelined. Just to touch on the original topic, I am getting duplicates on my author page. This is the author.php code :

<?php get_header(); 

if(isset($_GET['author_name'])
) :
$curauth = get_userdatabylogin($author_name);
else :
$curauth = get_userdata(intval($author));
endif;

if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>">
<?php the_title(); ?></a>,
<?php the_time("d M Y"); ?>
</li>
<?php endwhile; else: ?>
<p><?php _e("No posts by this author."); ?></p>
<?php endif; ?> 

<?php get_footer(); ?>

Gives me sometimes 3x and 4x results for some posts. This is after installing the co-author plugin, and this is for authors who posted in the past ( no new posts since plugin was installed )

@disagree Are your user_nicenames different than your user_logins? If so, here’s an outline of the problem and how to fix it.

Only the capitalization, e.g. user_login = ABC, user_nicename = abc
