First off, commands in this game are pretty bad, experiment with them in a test world before using it.
Try restarting your game again if you haven't, sometimes the command doesn't alter the config files.
Probably won't work but it's worth a try.
In saying this, to change settings, it's best to do it in the config. But try this next:
You'll need to find your eco folder
Typical:
C: program x86/steam/steamapps/common/eco
Mine personally:
D: steam/steamapps/common/eco
Open the folder "storage", and you should see two files and a folder called "backups". The files are your world save, keep em safe, Game.db and Game.eco (might be your world name). I'd save these somewhere.
Then open your backups folder, find the most recent folder BEFORE you typed the code and copy the .db and .eco files into "storage". Replace the old files or just paste them if you already deleted them.
Now launch your game and it should be restored to the backup.
If this doesn't work, I'd reinstall the game then put those two original files back in "storage" and try again, this should reset all config files, and restore your save.
If that doesn't work, then you'll have to find the config file that was changed from the command
