Solved Server Resets "online-mode=false"

Hi,
I'm running a craftbukkit-1.4.7-R0.1 server. I've run into a little problem.
When I try to set my online mode to "true", the server resets it to "false".
I thought it was a bug (it is a beta build) and downloaded the recommended build. Same problem but the serve says:

[WARNING] **** SERVER IS RUNNING IN OFFLINE/INSECURE MODE!
The server will make no attempt to authenticate usernames. Beware.
While this makes the game possible to play without internet access, it also opens up the ability for hackers to connect with any username they choose.
[WARNING] To change this, set "online-mode" to "true" in the server.properties file.

When I try to change it and reload the server it does the same thing but does not give me a WARNING.

I tried to remove ALL my plugins but that didn't help either. I tried starting a completely new server and it did the same thing.

I'm stumped, can someone please help?

 

Stop the server, change the properties, start it back up...

 

I've done that. The config says "true" but when the server comes up, it says the WARNING.

 

Did you save the config? Pm me your start.bat or start.sh

 

Try add -o true to your start file, eg;

Code:

java -Xms1024M -Xmx1024M -jar craftbukkit.jar -o true

 

-o true is there, I don't remember putting it there so can you tell me what it does?

 

It tells the server to always run in online-mode, regardless of what setting is in your server.properties

 

are you using any kind of a host or a GUI?

 

in the run/start.bat do edit and replace the true to false!

 

He wants it true, not false. Nice reading skills you got there

 

I just use a .bat file and run it in a command prompt window. If you need any more info, just say so.

 

Plugins? Maybe?

 

Plugins:
- Essentials (core, chat, and spawn)
- LogBlock
- LWC
- Multiverse (core)
- PermissionsEx
- WorldEdit

Those are all the plugins I have running right now. I have 4gb RAM allocated for the server too.

 

Delete the server.properties then let Bukkit remake it? It should then have 'online-mode=true'

 

Thanks for all the help guys, but I feel really slow. I just restarted my computer and started the server up and there's no warning.
Sorry to take your time
