Hi, this is a fresh install of 2.0.6 hosted on AWS.
When I built the site the sample content was there, I could navigate to the course pages.
After I poked around a bit, suddenly all but the home page results in a 404.
If I create a new post and save the draft, I can see it on preview. But when I publish it, the permalink does not work. I tried switching the permalink structure and it did not help.
Site is http://classesdev.catapult.co/
Please try re-saving the permalinks to postname.
If it does not help then please share the admin credentials with us to check the issue on your site.
PS:Please mark your reply as private while sharing the admin credentials.

This is a very common issue in wordpress and is caused due to disabled mod_rewrite functionality on server .
Please contact your webhost to enable the mod_rewrite .
