Hi
1. If you use child theme, you can put the following custom PHP function into functions.php file
function dgwork_post_author(){
global $dgwork_option;
if ( isset($dgwork_option['post_author']) && $dgwork_option['post_author'] == '1' ):
?>
<!--Author-->
<section id="author_vcard">
<h3 class="author-title section-title"><?php esc_html_e('About Author','dgwork');?></h3>
<div class="avatar"><?php echo get_avatar( get_the_author_meta( 'ID' ), 80 ); ?></div>
<p><strong><?php the_author_meta('nickname'); ?></strong> </p>
<?php the_author_meta('description'); ?>
<?php if(class_exists('ThemeVan_Shortcodes')):?>
<p><span class="social_icons"><?php do_action('tmvs_author_social_profile');?></span></p>
<?php endif;?>
</section>
<?php
endif;
}
2. You can disable the comment section by WordPress default feature, just quick edit the post, then cancel the “allow comment” checkbox. https://www.dropbox.com/s/poy2m78cefscwt8/Screenshot%202017-06-11%2001.42.03.png?dl=0
