Missing Author, entry title, missing updated.

These codes will generally fix the errors

<h2 class="entry-title"><?php the_title(); ?></h2>

<span class="vcard author post-author"><span class="fn"><?php the_author(); ?></span></span>

<span class="post-date updated"><?php the_date(); ?></span>

But I can’t seem to locate these codes or similar in the single.php file.

<h2><?php the_title(); ?></h2>
<?php the_author(); ?>
<?php the_date(); ?>

You can find the tags in the single.php …

Title – <h1><?php the_title(); ?></h1>
Meta data – at the bottom:

<p class="post_meta">
	<span class="calendar"><?php printf('<a href="%1$s">%2$s</a>', get_permalink(), get_the_date()); ?></span>
	<span class="author"><a href="<?php echo get_author_posts_url(get_the_author_meta('ID' )); ?>"><?php echo __('By ','Aqua');?> <?php the_author_meta('display_name'); ?></a></span>
	<span class="comments"><?php  comments_popup_link( __('No comments yet','Aqua'), __('1 comment','Aqua'), __('% comments','Aqua'), 'comments-link', __('Comments are Off','Aqua'));?></span>
	<span class="tags"><?php the_category(', '); ?></span>
</p>

I fixed “Missing Author” and “Missing updated”, but I’m not able to fix “entry title”, which does not appear within Google Structured Ddata Testing Tool.

Please, see below how I edited the single.php:

<div class="sixteen columns">
 <?php boc_breadcrumbs(); ?>
     <div class="page_heading"><h1 class="entry-title"><?php the_title(); ?></h1></div>
</div>

Regarding the meta, I edited in this way:

<p class="post_meta">
<span class="post-date updated"><?php printf('<a href="%1$s">%2$s</a>', get_permalink(), get_the_date(), get_the_time()); ?></span>
<span class="vcard author post-author"><span class="fn"><?php echo __('By ','Aqua');?> <?php the_author_meta('display_name'); ?></a></span>
<span class="comments" style="display:none"><?php  comments_popup_link( __('No comments yet','Aqua'), __('1 comment','Aqua'), __('% comments','Aqua'), 'comments-link', __('Comments are Off','Aqua'));?></span>
<span class="tags"><?php the_category(', '); ?></span>
</p>

It broken a little bit the layout, but it seems to work well.

Please, may you help me to fix the “Title”?
Thank you.

I was checking my website in Google Webmaster Tool and I noticed that all my posts had three errors: “Missing: author”, “Missing: entry title”, “Missing: updated” (see this screenshot).

I investigated a little bit and I found this resource: https://wpcolt.com/fix-hentry-errors-wordpress/.

After editing the single.php file I resolved “Missing: author” and “Missing: updated” issues,but “Missing: entry title” error is still there (see this screenshot).

I’m using a child theme, sure.

Thank you!

<div class="page_heading"><h1><?php the_title(); ?></h1></div>

How to edit this:

<div class="sixteen columns">
 <?php boc_breadcrumbs(); ?>
     <div class="page_heading"><h1 class="entry-title"><?php the_title(); ?></h1></div>

Google says:
Missing title: which means that the item (page/post) missing the “entry-title” CSS class.
For this, you need to look for your post/page title and add class=”entry-title” for example: <h1 class="entry-title">The title</h1>

<h1 class="entry-title"><?php the_title(); ?></h1>

<div class="sixteen columns">
 <?php boc_breadcrumbs(); ?>
     <div class="page_heading"><h1 class="entry-title"><?php the_title(); ?></h1></div>

Thanks for your patience
