This version of PartyMe has no server settings file. The Beta of the mod actually does, but they are both write in totally different way and doesn't work together.

I highly suggest going for [Beta] PartyMe rather this one. You actually have less options for marker or keybinds, but on server side it will run smoother.

If you're using the Beta, the file path is: $profile:PartyMe/config.json, it can be created at launch of the server for the first time. Howewer, you'll need to create the folder for it.
