Permalink Default Page Error

I’m currently trying to get my permalink default page working. Currently when I do http://www.website.com/home and http://www.website.com/about is working. In the backend I set the Reading Setting > Static Page to Home.

When I go back to http://www.website.com it doesn’t work and give me a 404 – File or directory not found.

Thank you in advance for your time and assistance. Much appreciated.
