Your site wont load for me.
If you go into the ‘menu’ section of wordpress dashboard you can create a custom nav which would remove any duplication.
http://www.dromberg.se/ ?
It looks like there is something wrong with your a tags…
<ul id="menu">
<li><a class="home" href="http://www.dromberg.se/"</a></li>
<li><a class="personal" href="http://www.dromberg.se/personal/"</a></li>
<li><a class="contact" href="http://www.dromberg.se/kontakt/"</a></li>
</ul>
Should be…
<li><a href="http://www.dromberg.se/"></a></li>
<li><a href="http://www.dromberg.se/personal/"></a></li>
<li><a href="http://www.dromberg.se/kontakt/"></a></li>
Carolyn – in what pages did you found the code?
