Frequently Asked Questions about WoW Mangos Error Message

Since there still many people who still having problem with their Mangos Server, based from the number of comments i received so far on this site. I’ll try my best to explain what all those error messages means, so here goes the lists

Note : If you’re using older mangos release, i’d suggest you to upgrade first because i won’t be able to answer your question if you’re using a historic release or old release. And currently this is based on my latest 4524 (if you’re using my previous 4488, or 4505 release … try to upgrade first because in 4524 i’ve already created an even easier batch script so you don’t really need to know about varios MySQL Queries command)

As a side note, if you’re running World of Warcraft TBC version below 2.1.3, i can’t give you any support on this … unless you’ve upgraded your WoW Client into 2.1.3 or 2.2

1. The most frequently asked question is not exist error message so mangos can’t be started ?

The answer to that question is … did you run the extract-map.bat from your World of Warcraft Installation Directory ? and if so … did you wait until the process finished completely without interrupting it. And it’ll take a while to extract all maps completely but that’s depend on your computer specs. It took 6 minutes for the process to finished completely on my computer, and oh … i’ve done the extraction process for about 5 times or more, and i can locate the just fine by using Windows Search Function which mean the extraction process is successful

Vmap example and 4331 map

If you’re sure you can locate the using your Windows Search Function, try looking at the datadir section of your mangosd.conf (if you’re using my 4524 release you can just use the reaper-x-mangos.bat to edit the datadir) or you can edit it by yourself using Notepad / Wordpad or other text editor and make sure the datadir point to where you put the Maps, DBC and VMaps directory

For example if you put like on below image for example ( I:\WoW\Data )

Mangos datadir

You should write DataDir = “I:\WoW\data” as your datadir (with quotes and don’t copy paste from here because this software automatically transform quotes into curly quotes)

Also DataDir = “I:\WoW\data” or DataDir = “I:/WoW/data” is just the same, i can use them both without problem, although on some system you should use backslash (“/”) from various response

2. Could not find 001_33_39.vmdir or other vmdir related error message ?

Did you copy all files inside Tools\VmapExtractAssembler into your WoW installation directory ? and then run the makevmaps_SIMPLE.bat and wait until the process finished without interrupting it ? and one more thing :

if you see vmap_assembler.exe buildings vmaps splitConfig.txt displayed on the command prompt screen, you just need to wait until you can Press Any Key To Continue message appear on your screen

3. ERROR:Could not connect to MySQL database at ?

That error message mean, you haven’t started the MySQL process yet … did you follow my previous guide on how to install MySQL ? and another thing to keep in mind that you need Administrator Privilege in order to do that, and if you still get error message saying can’t bind or something. Make sure that :

There’s no mysql process running in background, to check it open the task manager and then look for mysql under the process list tab. This thing can happen if you previously using repack that include mysql into their repack

4. Could not locate locale-enUS.MPQ, patch-enUS-2.MPQ, or other enUS-MPQ related error ?

That mean you’re using different WoW version, you just need to edit extract.bat inside the DBC Extractor directory like below :

mpqe /d “.” locale-enUS.MPQ *.dbc
mpqe /d “.” patch-enUS.MPQ *.dbc
mpqe /d “.” patch-enUS-2.MPQ *.dbc

Into the correct MPQ filename, for example locale-enGB.MPQ

And another note, you’ll need .NET Runtime 2 in order to run the DBC Extractor

5. Friends could not connect from LAN or stuck in realm loop ?

Make sure you’ve change the realmd.realmlist ip address into your lan Address, and if you’re currently have mangos running close it first before adjusting it into your IP Address

Because some people keep having problem with changing the ip address into their lan ip address, i’ve created the batch script in my 4524 release so you just need to write your LAN IP address when asked (by choosing the LAN option from the menu first of course) … that’s it

But if you don’t know what is your lan ip address … i can’t help you with that

That’s it for now … because that’s basically the most frequently asked questions to me via the comment box ;) … hope this will help you solve your problem

  1. If anyone gets an error that the DBC extractor cannot find the following MPQ file:

    Could not locate expansion-local-enUS.MPQ

    …it may be due to the way the extract-enUS.bat file is setup. You’ll need to edit the second line in the extract-enUS.bat file to read as follows:

    mpqe /d “.” expansion-locale-enUS *.dbc

    The difference is the ‘e’ at the end of the word locale which is missing in the .bat file that is included with the Reaper Mangos 5953 installer.

  2. I get the error.

    Error in creature_template_addon table, probably sql format was updated (there should be 8 fields in sql)

    How do i fix this please?

  3. Hi Reaper!
    Great guide, but I have a question: I’m running Vista, and I’ve got to the point where the server is running fine.

    Unfortunately I can’t connect: is set to, but it always says ‘unable to connect’. Any ideas?

  4. ok, Im using the most up to date Mangos, and Im at the 2.3.2 vers of WoW, It wont allow me to update to 2.3.3 for some reason, says
    Patch can’t be applied because it is missing data for: “enUS”. If this problem persists, you may be able to solve it by uninstalling and then reinstalling the game. If you are unable to correct this problem, please contact Blizzard Technical Support. (SetLanguage)

    and also, it cant find that
    and during the extraction process, it gets to 41% everytime, then crashes.
    Can someone help me?

  6. Hi there.. I’ve been noticing that the mobs and bosses aren’t casting any spells. I get errors like “Aura::TriggerSpell: Spell 38794 have 0 in EffectTriggered[0], not handled custom case?” that can only suggest that the spell was being called by the program but its not executed. Any help with this will be greatly appreciated.

  11. also,
    now i tried to move te old maps (v. 2.2.3) into my data folder the server loads!!

  12. hi all,
    i can locate but in an other map from version 2.2.3.
    and when i extract maps there only maps like this: map_1 etc.
    so do you think the extractor dont work?

    srry about my bad englisch, thats because im not englisch

  13. Hey guys nvm about the First Error i fixed it.

    Update : Error was due to not having expansion and resovled by editing this line in the mangos.conf :# Allow server use expansion content
    # 0 (not check expansion maps existence, not allow wisit its, not allow create new race characters, ignore account expansion setting)
    # Default: 1 (check expansion maps existence, and if client support expansion and account have expansion setting then allow visit expansion maps, allow create new races character)
    Expansion = 1 : simply switch the number to 0 and it will skip it if you want a classic server.
