Pro Site not showing a Table, what am I missing?

Hello WPMUdev's

I have installed Pro Site and configured it. It generates me a site. The site has a title but is empty. If I add my Pro-Site site to the website (in the menu) and give it a designe in the theme (headwaythemes) it shows me the titel but no table.

Please can you help me what I'm missing? Is there some shortcodes I have to place? I couldn't find anything. Please point me to the right direction.

I have granted Access to you.

Thank you very much for your help.
Greetings
Marc
