How to Fix Mods Not Loading on Your DayZ Server

Note:

Most DayZ mod-loading issues come from three common sources: wrong mod order, missing keys, or incorrect startup parameters.

1. Restart Your Server After Adding Mods

DayZ never loads new mods unless the server has been fully restarted.

A simple ‘Stop → Start’ is required (Restart is not always enough).

---

2. Check the ‘Startup’ Tab

---

2.1 Select the ‘Startup’ tab

---

2.2 Navigate to ADDITIONAL MODS

Make sure:

• Mods are listed using this format:

@ModName;@AnotherMod;@CF;@VPPAdminTools

• No spaces between entries (some hosting panels break the load if spaces exist)

• No trailing semicolon at the end
  – Correct example:
  @CF;@VPPAdminTools;@WeaponReduxPack
  
  – Incorrect examples:
  @CF; @VPPAdminTools (space after ; )
  @CF;@VPPAdminTools; (ends with ; )

---

3. Make Sure the Mods Exist in the Server Files

---

3.1 Select the ‘Files’ Tab

Navigate to → /home/container/

You should see a folder for every mod you added in ADDITIONAL MODS, such as:

@CF
@VPPAdminTools
@1559212036
@YourModName
@WorkshopID

If a mod folder is missing, it means the server could not download it.

How to fix missing mod folders

• Remove the mod from the ADDITIONAL MODS field
• Stop → Start the server
• Add the mod again in ADDITIONAL MODS
• Stop → Start the server once more
  (this forces the Workshop download)

This ensures the mod is downloaded cleanly and its folder and keys are created correctly.

---

4. Check for Missing or Wrong Mod Keys

DayZ will not load mods if their .bikey file is missing or outdated.

Navigate to the keys folder /home/container/keys

Make sure that:

• Every mod you installed has a corresponding .bikey file here

• No old or duplicate keys exist for the same mod

If keys are missing:

• Delete all old keys
• Restart the server
• The panel will re-install the correct ones automatically
  
  

---

5. Check Steam Workshop Version Mismatch

This is one of the most common causes.

If you have a newer version locally than the server, the server will fail to load the mod.

Fix:

• Stop your server

• Enable ‘AUTOMATIC UPDATES’ (Startup tab)

• Start the server again

This forces Cybrancee to download the latest Workshop version.

---

6. Verify That CF Is Installed (Required for Most Mods)

Many mods require CF or Community Framework.

If CF is not loaded first, mods won’t load.

Make sure the order in ADDITIONAL MODS begins with:

@CF;@VPPAdminTools;@Mod1;@Mod2

---

7. Check the Server Console for Errors

Open the Console tab and look for red error lines such as:

• ‘Missing dependency: CF’

• ‘Failed to load mod’

• ‘Key mismatch’

• ‘Addon script compilation error’

This will tell you exactly which mod is failing.

---

8. Clear Compiled Mod Cache (Advanced Fix)

Some mod issues occur when DayZ generates corrupted compiled data.

You can safely delete the “mpmissions/DayZOffline.[map]/storage_1” folder
ONLY if the issue is related to persistence or mod-generated world data.

DayZ will rebuild all necessary files on restart.

Important:
This does NOT delete the map or server configs — only world data that DayZ can regenerate automatically.

---

9. Check for Invalid Characters in Mod Folder Names

Folder names must match EXACTLY the Workshop folder name.

• Correct:

@BuildAnywhere

• Incorrect:

@buildanywhere
@BuildAnyWhere (typo)
