Hi Dani,
I must be doing something wrong in creating the custom Site Sculptor. I've created a simple template using CSS Sculptor and tried to create a site with SS. However, I've found the same problem as above with the nickusborne file. As you can see from the attachments, the Home page has the navigation bar, but none of the content page has the navigation bar. I'm not sure what I'm missing or doing wrong.
