Updated to WP 2.9.1 and now categories won't show.

Just like the title says, I updated WP to 2.9.1 and now the categories show "no categories".

Here's the code that shows the sidebar and what should be the categories:

if ( is_single() ) :
global $post;
$categories = get_the_category();
foreach ($categories as $category) :
?>
    <li>
      <h2><?php _e('More from this category','branfordmagazine');?></h2>
      <ul class="bullets">
        <?php
$posts = get_posts('numberposts=10&category='. $category->term_id);
foreach($posts as $post) :
?>
        <li><a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>
          </a></li>
        <?php endforeach; ?>
        <li><strong><a href="<?php echo get_category_link($category->term_id);?>" title="<?php _e('View all posts filed under','branfordmagazine');?> <?php echo $category->name; ?>"><?php _e('Archive for','branfordmagazine');?> '<?php echo $category->name; ?>' &raquo;</a></strong></li>
      </ul>
    </li>
    <?php endforeach; endif ; ?>
    <?php if ( is_home() ) { ?>

    <?php } ?>
    <li>
      <h3><?php _e('Browse Categories','branfordmagazine');?></h3>
      <ul class="subnav">
       <?php wp_list_categories('orderby=order&hide_empty=1&title_li=&exclude=7');?>
      </ul>
    </li>

It will not show up in single posts or pages either but in single posts it will show "more from this category" and show the correct posts.

Suggestions?

Did you disable all plugins before updating?

No, I only have two active.

But - I did update one of them and it's working now. Rather odd but eh, I'm glad it's working.

Thank you for pointing me in the right direction.
