Well, I fixed it. Feel free to change the code in the plugin where it has.
function sharebar_filter($input){
global $post;
$code = array('[title]','[url]','[author]','[twitter]');
$values = array($post->post_title,get_permalink(),get_the_author(),get_option('sharebar_twitter_username'));
return str_replace($code,$values,$input);
}
Change it to
function sharebar_filter($input){
global $post;
$code = array('[title]','[url]','[author]','[twitter]');
<em>$meta = strip_tags($post->post_title);
$meta = str_replace(array(<strong>ELEMENTS_HERE</strong>),array(<strong>REPLACEMENTS_HERE</strong>), $meta);</em>
$values = array(<em>$meta</em>,get_permalink(),get_the_author(),get_option('sharebar_twitter_username'));
return str_replace($code,$values,$input);
}
