For other configuration files you can use the control panel file manager or use an FTP client, you will find them in the Configs folder of your server.
You will see that some files have the extension .eco.template; these are files with a default configuration. If you want to modify the parameters they contain here is how to do it:
- Download the file to modify
- Rename it to .eco (for example Difficulty.eco.template will become Difficulty.eco )
- Edit it to modify the parameters it contains at your convenience
- Upload the .eco file thus created in the Configs folder of your server
- Restart the server to apply the new settings
