To show the information about the post author, first open the single.php file in your WordPress theme and find the where the content is displayed:
<?php the_content(”); ?>
Then add the following codes in your theme:
<?php if ($lw_post_author == “true” && is_attachment() != TRUE) : ?>
<div >
<?php echo get_avatar( get_the_author_id(), ’28’ ); ?>
<h4>
<?php _e(‘Author’,’lightword’); ?>: <a href=”<?php the_author_url(); ?>”><?php the_author(); ?>
</a>
</h4>
<?php the_author_description(); if(!get_the_author_description()) _e(‘No description.
Please update your profile.’,’lightword’); ?>
</div>
<?php endif; ?>
This will include the information about the post author on your site. Simply update your style.css to change the style that you want.
