Ok, so recently I came across a problem(minor or bigger?). I had downloaded a repack, and was about to do some "offline" developing. Though when I tried to log in it tells me that I have the wrong patch. I figured out that the repack was 3.0.8 while I had updated to 3.0.9. Now I will show you how I fixed it:
Open Up your WoW Launcher. Then look in the top right corner. There you will see something like:
"World of Warcraft v[patch numbers here(ex 3.0.9)] [Client Build number(ex 9551)]
The 9551 is the number you will need. Remember it.
Open up your logonserver file and search for:
Now you modify your client MaxBuild to the Client Number you previously found. Now your server will be able to accept people with the latest patch.Code:<Client MinBuild = "XXXX" MaxBuild = "XXXX">
Doing this will only make the server playable. This will not include the changes made in the patch. I also don't know if this will work with major patches ex: 3.0.0 - 3.1.0
May the Force be with you
