RedProtect can't find config file

I’m creating a SpongeForge server with RedProtect as my anti-grief plugin. I’ve loaded RedProtect onto my server but cannot find the config file. RedProtect is definitely working and being recognised on the server but I have no idea where the config file is and can’t find any information regarding the config file apart from what to do when you open it.

It is in the same place where all other config files are placed.
