Is there an author.php in your theme that you could debug?
Sorry completely forgot to mention that yes i do have an author.php file.
For the most part, i’m using the code from ‘Sample Template File’ section in codex page for Author Templates. Just adapted the html a little. The code is now:
<?php get_header(); ?>
<div id="bg_5" class="bg_bands"><!-- Background Band 5: Start -->
<div class="main_area"><!-- Main Individual Content Area: Start -->
<div id="content"><!-- CONTENT: Start -->
<h1 style="color:#f60; font-size:40px;">THIS IS AUTHOR.PHP TEMPLATE</h1>
<!-- This sets the $curauth variable -->
<?php
$curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));
?>
<h2>About: <?php echo $curauth->nickname; ?></h2>
<dl>
<dt>Website</dt>
<dd><a href="<?php echo $curauth->user_url; ?>"><?php echo $curauth->user_url; ?></a></dd>
<dt>Profile</dt>
<dd><?php echo $curauth->user_description; ?></dd>
</dl>
<h2>Posts by <?php echo $curauth->nickname; ?>:</h2>
<ul>
<!-- The Loop -->
<?php query_posts( array(
'post_type' => array(
'videos',
'events',
'courses',
'articles',
'shorts',
'poetry',
'revert-stories',
),
'paged' => $paged ) // for paging links to work
);
?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>">
<?php the_title(); ?></a>,
<?php the_time('d M Y'); ?> in <?php the_category('&');?>
</li>
<?php endwhile; ?>
<?php wp_pagenavi(); ?>
<?php else : ?>
<p><?php _e('No posts by this author.'); ?></p>
<?php endif; ?>
<!-- End Loop -->
</ul>
</div>
</div><!-- CONTENT: End -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>
