Currently have a VPS server. In Cpanel the main domain is robertgfrancis.com. I already have several addon domains with wordpress installed and their folders are also in the public_html folder. They all work fine. When I copy wordpress into the root of the public_html folder and go to robertgfrancis.com in my browser the install should start, but it doesn't. It gives me an "index of" page and list two folders. Please see attached pics. What could possibly be the problem.
