All Server Settings
Server settings decide how your world behaves when nobody is online, how mods load, how passwords work, and how forgiving the server is when something goes wrong. Treat them like operations policy, not just a wall of toggles.
The Major Settings Areas
| Security and access | Passwords, whitelist choices, anti-cheat posture, and who gets elevated permissions. |
|---|---|
| World behavior | Pause rules, sleep handling, corpse cleanup, and other settings that change the server's rhythm. |
| Networking | Connection limits, voice options, and how tolerant the server is of bad client conditions. |
| Mods and map stack | Workshop IDs, map order, and any setting that determines how clients sync with the server. |
Order To Tune Them
- Lock down access and backups first so mistakes are survivable.
- Configure map and mods before inviting players, because later changes are much more expensive.
- Tune world-behavior settings after a short live test, not before.
- Review networking and restart policy once the server sees real traffic.
What Causes Most Admin Pain
- Changing map order after the world already has active players.
- Giving moderators broad powers without an agreed process.
- Letting the config drift over time until nobody remembers why a value changed.
Verified 2026 Detail
The official stable-versus-unstable split matters here because server settings often outlive the branch they were created on. A config that was sensible on one branch can become confusing on another, especially once map order, workshop content, and multiplayer defaults have drifted for months.
Current Official Note
The official Project Zomboid site still presents stable and unstable as separate release tracks. When you review server settings, keep that split in mind because defaults, new options, and multiplayer assumptions can differ between the established stable branch and current Build 42 testing.
Settings that no longer exist
Options get removed, but their descriptions can survive in the game's translation files long afterwards, which is how dead settings end up in guides that look authoritative. Most of those descriptions belong to settings that moved to the sandbox options and still work there. A few belong to nothing at all. The clearest example is ZombieUpdateRadius, still recommended everywhere as the fix for zombies vanishing on a server, and absent from the compiled code of both shipped server builds. Zombie culling and the No Mo Culling mod works through the evidence and lists what the current build actually exposes instead. Before you copy a setting out of a forum post, confirm it appears in the config your own server generates.
Two groups of settings catch people out more than the rest. The Voice tab holds exactly four options and nothing else, covered in the VOIP guide. The ten anti-cheat options are all worded as disable switches, so turning one on removes a protection rather than adding one.
