After click on load more, share buttons stop working i use Add to Any plugin for share, and it works perfect on post who are not in load more div. I put in repeater template code for share, you can see how repeater template looks:
<div class="col-md-4" style="margin-top:20px">
<h6 style="font-weight:bold;margin:0px;">Recent</h6>
<p class="entry-date" style="margin:0px"><?php echo get_the_date(); ?></p>
<?php if ( function_exists( 'ADDTOANY_SHARE_SAVE_KIT' ) ) { ADDTOANY_SHARE_SAVE_KIT(); } ?>
<a href="<?php the_permalink();?>"><h2 style="margin-bottom:0px"> <?php the_title(); ?></h2></a>
<br/>
<?php $short_desc = get_post_meta(get_the_ID(), 'birds_portfolio_short_desc', TRUE); ?>
<p class="hp-short-desc"><?php echo $short_desc; ?></p>
<a href="<?php the_permalink();?>" style="text-decoration:underline">READ MORE</a>
<?php if ( (function_exists('has_post_thumbnail')) && (has_post_thumbnail()) ) { ?>
<figure class="effect">
<a href="<?php the_permalink();?>"><?php the_post_thumbnail("full"); }?></a>
</figure>
</div>
