Author Link Going to Home Page Instead of Author Page

On my site we have multiple authors. I followed the directions that I found here on how to set this up but something is wrong. When you hover over each link it says https://www.sitename.com/blog/author/authorname/ but when you click on it you go to the home page.

I was able to set it up so under each post (except on home page) it displays the Author’s Name and that would link to an author profile page with:

<p>Written by <?php the_author_posts_link(); ?> | <?php the_time('F j, Y'); ?> </p>

Then I created an author.php file:

<?php get_header(); ?>

<div id="content">

   <div id="contentleft">

<!-- This sets the $curauth variable -->
<?php
if(isset($_GET['author_name'])) :
$curauth = get_userdatabylogin($author_name);
else :
$curauth = get_userdata(intval($author));
endif;
?>
<h3>About: <?php echo $curauth->display_name; ?></h3>
<p><strong>Website:</strong> <a href=”<?php echo $curauth->user_url; ?>”><?php echo $curauth->user_url; ?></a></p>
<p><strong>Profile:</strong> <?php echo $curauth->user_description; ?></p>
<h3>Posts by <?php echo $curauth->display_name; ?>:</h3>
<ul>
<!– The Loop –>
<?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>
</li>
<?php endwhile; else: ?>
<p><?php _e(’No posts by this author.’); ?></p>
<?php endif; ?>
<!– End Loop –>
</ul>
</div>

<?php include(TEMPLATEPATH."/sidebar_right.php");?>

</div>

<!-- The main column ends  -->

<?php get_footer(); ?>

What am I missing?
