On a Valheim server, BepInEx keeps every mod’s settings in the BepInEx/config folder as a .cfg file named after the mod’s ID (GUID), and its own loader settings in BepInEx/config/BepInEx.cfg. A mod creates its config file the first time the server starts with it. Edit the file in the File Manager, save, and restart the server. To disable a mod, switch it off on the Mods page and restart.

​
How to change a mod’s settings

1

Start the server once

Install the mod and start the server. Mods that come with settings put them in BepInEx/config on first load.
2

Stop the server

Stop the server so your changes aren’t overwritten while it runs.
3

Edit the config file

Open the File Manager, go to BepInEx/config and open the mod’s .cfg file. Each setting has a comment above it with its description and default value.
4

Save and start

Save the file and start the server. Check the console for errors.
A setting looks like this:
Some mods send the server’s settings to players when they join; others need each player to change their own file. The mod’s Thunderstore page says which.

​
How to disable a mod or BepInEx

BepInEx itself is part of your server (“Valheim BepInEx”). With no mods switched on, the server plays like the normal game. If you want BepInEx removed entirely, open a ticket.

​
How to find which mod causes an error

  1. Read the console or server logs while the server starts. BepInEx names each plugin as it loads, and errors usually mention the mod.
  2. Switch half of your mods off on Mods, restart and test.
  3. Keep halving until you find the mod, then update or remove it.

Frequently asked questions

​
Where is the BepInEx config folder on a Valheim server?

In BepInEx/config, open it with the File Manager or SFTP.

​
Why is there no config file for my mod?

Not every mod has settings. If it has, the file appears after the server has started once with the mod.

​
Can I reset a mod’s settings?

Stop the server, delete the mod’s .cfg file and start the server. The mod writes a new file with its default values.
