Wireless Mining Turtle is unable to place Fir Saplings?

Hey!
So I wanted to use Sethbling's Autowood program wich I copied into my Turtle, but my problem is that it is unable to place the saplings. It runs properly, just doesn't place them, and then bonemeals the ground. But why? (I placed them in slot 15 where they are supposed to be placed.)
The code:

local function replant()
  turtle.select(15)
  turtle.suck()
  turtle.place()
  turtle.turnLeft()
  turtle.suck()
  turtle.forward()
  turtle.suck()
  turtle.turnRight()
  turtle.suck()
  turtle.place()
  turtle.turnRight()
  turtle.suck()
  turtle.place()
  turtle.turnRight()
  turtle.suck()
  turtle.forward()
  turtle.suck()
  for slot=3,7 do
	turtle.select(slot)
	turtle.drop()
  end
  turtle.turnLeft()
  turtle.turnLeft()
  turtle.select(15)
  turtle.place()
  while turtle.compare() do
	turtle.select(16)
	turtle.place()
	turtle.select(15)
  end
end

Thanks in advance for the help,

Split into new topic.

Assuming slot 16 contains the bonemeal, it should never use any of that, as going by what you're saying it'll never detect a sapling in front of it to use it on.

Can you plant saplings where the turtle wants to?

Can the turtle place other blocks at those locations?

If you make a program that only consists of "turtle.place()", does that work?

Hey!
Thanks for the help, sorry for the slow answer, I was on a holiday.
So:
1: Yes, I can.
2: No, it cannot.
3: No, it doesn't.

Usually this means there's some sort of plugin on the server affecting matters. Eg, PermissionsEx.

So should I ask an admin?

Yup.
