Hello there !
Could you please provide the php script to show author box on both posts and pages?
I have already added this script provided by Tom:
<div class="author-box">
<?php global $post; ?>
<div class="avatar"><?php echo get_avatar( get_the_author_meta( 'ID' )); ?></div>
<h5 class="author-title">Written by <a href="<?php echo get_author_posts_url( get_the_author_meta( 'ID' ) ); ?>" title="Read more"><?php echo get_the_author_meta( 'display_name'); ?></a> on <?php echo generate_do_post_meta_item( 'date' ); ?></h5>
<div class="author-summary">
<p class="author-description"><?php echo wp_kses( get_the_author_meta( 'description' ), null ); ?></p>
</div>
</div>
