Notes (Required)

When I want to apply the configuration and save it, I get this error and then I get logged out of the server, the changes do not take effect.

I use this version, because the last one doesn't even allow me to edit server files in multiplayer, but this version gives me that problem. I use a linux based hosting server with ptero.
