single posts not showing author

yes i’ve contacted the theme author. no help.

on single posts, author names don’t display. example:
“Posted on Monday, October 21st, 2013 by in Album Reviews with 2 Comments”

between the “by” and “in”, author name + link is not displaying.

this is what the single.php looks like:

<?php get_header(); ?>
<div class="posticon">
<?php

$post_link = get_permalink();
$post_title = get_the_title();

?>
<?php if(has_post_format('aside')) { ?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-note.png"  class="postformat" /></a>
<?php } ?>
<?php if(has_post_format('audio')) { ?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-audio.png"  class="postformat" /></a>
<?php } ?>
<?php if(has_post_format('gallery')) { ?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-photo.png"  class="postformat" /></a>
<?php } ?>
<?php if(has_post_format('image')) { ?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-photo.png"  class="postformat" /></a>
<?php } ?>
<?php if(has_post_format('link')) {
    $values = get_post_custom( $post->ID );
    $post_link = isset( $values['link_post_url'] ) ? $values['link_post_url'][0] : get_permalink();
    $post_title = isset( $values['link_post_caption'] ) ? $values['link_post_caption'][0] : get_the_title();
?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-link.png"  class="postformat" /></a>
<?php } ?>
<?php if(has_post_format('quote')) { ?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-quote.png"  class="postformat" /></a>
<?php } ?>
<?php if(has_post_format('video')) { ?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-video.png"  class="postformat" /></a>
<?php } ?>
<?php if(get_post_format() === false) { ?>
<a href="<?php the_permalink(); ?>"><img src="<?php bloginfo('template_directory'); ?>/img/icon-post.png"  class="postformat" /></a>
<?php } ?>

</div>
<div id="main">
