I tried to implement your sample code into my site but the total favorites for the post doesn't show up. All I see is the "people like this post." text.
<b class="tapeViews"> <?php echo getPostViews(get_the_ID()); ?> <span class="statTxt">Views</span>
<b class="tapeComments"> <?php comments_number('0', '1', '%'); ?> <span class="statTxt">Comments</span>
<b class="tapeFavs"> <?php
$favorite_count_check = get_post_meta($post->ID, $key, true);
echo $favorite_count_check." people like this post.";
?> </b> </span>
As you see, I have the total Views and Comments, but cannot get the total favorites to display correctly.
