Fix hentry errors webmaster tools

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(); ?>

I see there are a lot of partial files so I’m not sure where to implement the changes.
