XP buying is broken since the latest version of the Essentials plugin refuses to take XP commands from the console – do not ask me why they changed it that way. I commented on a bug report that someone else already submitted. If you want to buy XP, comment on the report, maybe they answer it faster then :)

We don’t actually record the transactions, so there’s no way to reliably do that, unfortunately. :/
I would like to buy xp :)
That explains that… but… there are other ways to gain xp, so I don’t care…
