Hi there,
1. add this
.single .entry-utils{display:none;}
in your custom CSS box under Customize->Additional CSS.
2. Open part-social-sharing.php and replace everything with this
<?php if( in_the_loop() ): ?>
<ul class="socials">
<?php
$thumb_id = get_post_thumbnail_id();
$target = 'target="_blank"';
$facebook = add_query_arg( array(
'u' => get_permalink(),
), 'https://www.facebook.com/sharer.php' );
$twitter = add_query_arg( array(
'url' => get_permalink(),
), 'https://twitter.com/share' );
$whatsapp = add_query_arg( array(
'text' => rawurlencode( get_permalink() ),
), 'whatsapp://send' );
$pinterest = add_query_arg( array(
'url' => get_permalink(),
'description' => get_the_title(),
'media' => olsen_get_image_src( get_post_thumbnail_id(), 'large' ),
), 'https://pinterest.com/pin/create/bookmarklet/' );
?>
<li><a href="<?php echo esc_url( $facebook ); ?>" <?php echo $target; ?> class="social-icon"><i class="fa fa-facebook"></i></a></li>
<li><a href="<?php echo esc_url( $twitter ); ?>" <?php echo $target; ?> class="social-icon"><i class="fa fa-twitter"></i></a></li>
<?php if ( ! empty( $thumb_id ) ): ?>
<li><a href="<?php echo esc_url( $pinterest ); ?>" <?php echo $target; ?> class="social-icon"><i class="fa fa-pinterest"></i></a></li>
<?php endif; ?>
<li><a href="<?php echo esc_url( $whatsapp ); ?>" <?php echo $target; ?> class="social-icon"><i class="fa fa-whatsapp"></i></a></li>
</ul>
<?php endif; ?>
Let me know if this worked for you.
If you decide to proceed with this modification I would suggest you create a child theme, copy over the files you are editing and make the modifications there. This will allow your changes to survive future theme updates. If you directly edit the theme’s files, all changes will be lost once you update.
Have a look at this guide to learn more about child themes and how to create one https://www.cssigniter.com/ignite/beginners-guide-child-themes/
