Hi there,
At the end of each posts these social icons are meant to be used as sharers.
This means that your visitor will share your post to social media. Instagram does not have a sharing service and the RSS feed will be identical in all posts!
So, open entry-content.php and move
<?php get_template_part( 'part', 'social-sharing' ); ?>
after
<article id="entry-<?php the_ID(); ?>" <?php post_class( 'entry ' . $post_class ); ?> itemscope="itemscope" itemtype="https://schema.org/BlogPosting" itemprop="blogPost">
Then add this
article .socials {
float: none;
width: 100%;
text-align: center;
margin-bottom: 10px;
}
article .socials li {
display: inline-block;
float: none;
}
article .socials li a {
margin-left: 6px;
margin-right: 6px;
}
.entry-meta {
clear: left;
}
in your custom CSS box under Appearance ? Customize ??Additional CSS.
Finally open part-social-sharing.php and remove
<li><a href="<?php echo esc_url( $gplus ); ?>" <?php echo $target; ?> class="social-icon"><i class="fa fa-google-plus"></i></a></li>
and
<li><a href="<?php echo esc_url( $facebook ); ?>" <?php echo $target; ?> class="social-icon"><i class="fa fa-facebook"></i></a></li>
and add
<li><a href="your-feed" <?php echo $target; ?> class="social-icon"><i class="fa fa-rss"></i></a></li>
after
<li><a href="<?php echo esc_url( $twitter ); ?>" <?php echo $target; ?> class="social-icon"><i class="fa fa-twitter"></i></a></li>
