Hello. I am at the Database configuration page in the installation. I am completely lost at what to do at this stage. I do not know my database server hostname (I tried localhost and twoagegamingcom.fatcowmysql.com because that is fatcow told me) and I do not know my database username and password. I have not even created any databases or usernames in MySQL so I am not sure what to do here.
Talk with your host. When you signed up for a hosting plan, they should have included a database.
I don't know fatcow hosting solution, but it appears to me that their shared hosting uses some sort of custom control panel. Since they give you unlimited databases though, I am almost 100% sure you are required to create the database yourself. And I would guess that would be done through the control panel you can access after signing up for hosting.
