The no profiles thing is a separate issue, unrelated to what user you are using. This thread is discussing it No profiles available.
To create a non-root user for use in the web-ui depends on what version of linux you are running. I am running ubuntu and I created a user named mc by entering the following command into the command line.
adduser mc
This will start the user creation process for the user “mc”. During this process it will ask you for a password.
Do you know which version of linux you are using?
