Too stupid to activate gamemode

[Keena]

Hey there
we are having a multiplayer server on an Ubuntu (if this matters) and I seem not able to activate the ability to change one's gamemode.

No matter if I type "/gamemode 2" in ingame chat or in server console with "./server.sh command "player Keena gamemode 2" - it says "Das Ändern des Spielmodus ist in dieser Welt nicht zulässig." (Trans: Changing the game mode is not allowed in this world.)

Anything I am missing or doing wrong, please? 

Thanks  in advance and have a nice day!

Did you restart the server, in case you changed the allowance of creative mode after creating a world?  Maybe you even have to create a new world. I had the same problem once and either i restarted the server or created a new world with that permission set to true, can't remember exactly.

Mh yes, the server was restarted several times already.
I am not 100% sure anymore, but I thought I created the world already with 

"AllowCreativeMode": true,

Hoewever, isn't there any chance/workaround/fix to activate it, even after creating the world?
