Tonal WP theme Missing: author and Missing: update – help?

In verifying my site with Google, I received error messages regarding Missing: author and Missing: update.

Doing a Google search to find a resolve, I learned that I should replace <?php the_author(); ?> with <span class=”vcard author post-author”><span class=”fn”><?php the_author(); ?></span></span> but I cannot find any trace of author referred to anywhere in your single.php file.

Please advise on BOTH issues as one appears to be the single.php file while the other is apparently missing in the function.php file.

Thank you in advance.
