I'm having the same problem
I've recreated the site many times but always the same problem...no navigation. Please help! This is what the code looks like in my Top Navigation after running Site Sculptor.
<div class="art-nav">
<div class="l"></div>
<div class="r"></div>
<!-- InstanceBeginEditable name="Top Navigation" --><?php echo WA_getCMSContent($database_PowerCMSConnection, $PowerCMSConnection, 'Calendar' , 'Top Navigation'); ?><!-- InstanceEndEditable -->
</div>
There is no mention in there of CSS Menu Writer although I specified in Site Sculptor that that is where the navigation should be placed. All Site Sculptor has done is make it an editable region via the Content Management System. It's as though Site Sculptor just ignored my request to insert the navigation there.
