Yes il use Bungee

OK. You will need to go talk to them about how to set up your server correctly then.

Ok need il ask Zml?

Are you using Bungeecord?

If you are using Bungeecord, you will need to talk to that plugin's authors to get instructions on how to set up your servers when you have your server.properties file set to online-mode=false because PEX requires that setting to be set to true. PEX will not function correctly when that setting is false, and many bungeecord servers can have that set to true— I just don't know how to do it since I have never used Bungeecord.

If you are not using Bungeecord, you will need to change the server.properties file to online-mode=true in order for PEX to function correctly.

We (the PEX plugin, the author/programmer zml2008, and myself) do not support servers running in offline mode. We know that offline mode is required for hacked/illegal servers and clients, and do not support those either. (Not saying you're trying to do that, just sayin' we don't support those.)

Ask for Bungeecord help over here.
