Hi, May I know how to add author name appear right below the post title. Example below the post title – cat info by author name Oct 20, 2014

Hi,
To display the author under the post title, you can open the content-single.php file, then add the following code under line 9.

<p>By <?php the_author(); ?></p>

Also, if you want to remove the author section on the left hand, you can add the following code to the Header Code (Dashboard > Customize > Custom Code)

<style>.single-post .co-author { display: none; }</style>

Hope this helps !
