I changed the posts_loop_template.php to
<div class=”post hentry ivycat-post”>
<!– This is the output of the excerpt –>
<div class=”entry-summary”>
<!– This will output of the featured image thumbnail –>
<div class=”featured-image”>
“>
<?php the_post_thumbnail(array (500,9999), array(‘class’ => ‘alignleft’)); ?>
</div>
<?php the_excerpt(); ?>
</div>
</div>
and it resolved it
