Create Witchcraft and Wizardry server?

I have a problem: I wanted to play the Harry Potter Map (Floo Network - Witchcraft and Wizardry) with my friends and created a server (on server.pro). Then I copied and pasted the world from my .minecraft / saves folder… But the problem is that when we start the game we spawn in nothing. Does anyone know how to fix the problem?

Did you choose the world as active world (unless you have multiverse core, then main world)?
