Sidebar “Bullet Points” Help

Hi,

I’m very new to wordpress and not that clued up on PHP so please excuse me if this is really simple!

I have an error in my WP coding somewhere as a Bulletpoint seems to appear in front of my Sidebar Heading instead of just in front of the links as it should.

However this only happens in Internet Explorer – the site seems to load perfectly fine in Firefox.

Here are images from IE and Firefox:

Can anyone shed any light on this …

This is the code from sidebar.php:

<div id="sidebar">
 <ul>
  <li><h2>About</h2>
   <ul>
   Port Group are a UK Based Fashion Importer, Exporter,& Distributor to the Wholesale & Retail Clothing Industy.
   </ul>
  </li>

<ul>
<?php
wp_list_pages('sort_column=menu_order&title_li=<h2>' . ('Pages') . '</h2>' ); ?>
</ul>

<?php if (function_exists('wp_theme_switcher')) { ?>
<li><h2><?php _e('Themes'); ?></h2>
<?php wp_theme_switcher(); ?>
</li>
<?php } ?>

  <li><h2><?php _e('Categories'); ?></h2>
   <ul>
    <?php list_cats() ?>
   </ul>
  </li>

  <li><h2><?php _e('Links'); ?></h2>
   <ul>
    <?php get_links('-1', '<li>', '</li>', ''); ?>
   </ul>
  </li>

 </ul>
</div>
