Bug in course navigation?

Hello,
When I try to navigate to my site’s only course:
http://jacobsugerman.byethost33.com/courses/workplace-english/
I’m instead directed back to the homepage.
Only by going to a lesson, e.g.:
http://jacobsugerman.byethost33.com/courses/workplace-english/lessons/communicating-with-your-boss/
can I see the course content and other lessons. It’s possible I accidentally changed a setting on Learnpress, but after resetting each setting, the problem persists. Any help would be greatly appreciated.
Thanks,
Jacob
