How do I make a creative private multiplayer server? I've heard that you must go to the server properties and change the gamemode to 1.. But that didn't work.
First off, this is the wrong forum for that. You may get more support if this gets moved to the Server Administration forum.
Secondly, did you save the server.properties file after you changed it? Still as .properties and not as .txt or anything?
Thirdly, have you tried deleting your player.dat file from the [ServerFolderName]/world/players folder? That may help. Otherwise, try using the in-game command /gamemode [user] 1 to switch you or another player to Creative mode (Where [user] is your Minecraft username: /gamemode dragon199569 1 would switch a player with the username dragon199569 to Creative)
Lastly, was your server working before you tried to switch? If it wasn't, then you may want to figure out what your issue was for that before you know if it is working in creative mode or not.
