I setup multisite on my wp. I went step by step.
When I finished, I did a test run - Got:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

I called godaddy. They told everything looked fine on their end, to contact developer.
So I'm here now. The site is bookyourbarber.com
