I made it work in the Game.ini file.
Just had to put the following at the start:

[/Script/ShooterGame.ShooterGameMode]

So, as an example, your Game.ini should look like this:
 

[/Script/ShooterGame.ShooterGameMode]
PlayerDefaultNoDiscoveriesMaxLevelUps=99
bClampHomeServerXP=false
ClampHomeServerXPLevel=99

I am still stuck at level 8

Tried to put the above lines in my Game.ini and no difference.

I don't have a DefaultGame.ini

So i also have a private server and stuck at level 8 because of the freeport.  Buying another tile/server is not an option at this stage.
I have added the following lines to my GameUserSettings.ini file but still stuck at level 8 :(

PlayerDefaultNoDiscoveriesMaxLevelUps=100
bClampHomeServerXP=False
ClampHomeServerXPLevel=100

HurricaneJack; any more pointers?  Also, I know you said to add it to the Game.ini file but that one is empty for me.
