I was able to fix my own issue and here is how I did it.
I changed my management username back to [B]‘fog’[/B]
It looks as if you are [B]NOT[/B] allowed to change the username. The username [B]MUST[/B] be set as [B]‘fog’[/B]
You [B]MUST [/B]also rename the fog user account created within Ubuntu to match the password within the web interface. (#sudo passwd fog)
Maybe we can create some sort of sticky thread on this and common TFTP and SQL issues concerning the config.php file. I see this all over the web but no real answers.
I hope all foes well with whoever is reading this!
