Hello,
I expected the quickstart package to install a clone of demo site except the images which will be replaced by placeholders. But it seems that the installation is quite different than the demo on your site. The menus, articles etc. present on your demo site have not been created when I installed the quickstart package. Also some modules are not having html content which showcases the modules as present in your demo site and also since the menus are missing the modules are not at all visible. Please check the quickstart package available for download on your site as its far true from starting quickly.
