Header and many components missing in Open Social Just installed Open Social:
https://www.drupal.org/project/social

The problem is that there is no content on the front page. No header or other blocks. I have reviewed videos of installation on YouTube, and notice that there is a header, and many other blocks available by default immediately after installation. Why does my new instance of Open Social have nothing on the home page?

I followed the install instructions on the module page:
https://www.drupal.org/project/social
Generating demo content is optional but recommended. 
Follow these instructions on generating demo content (Drush support only for now).
