unknown SCFTYPE error

Hi,
When I try to run mp2 calculations on the following geometry the code crashes.

geometry units angstrom
  #symmetry c1
   O 20.591 27.211 26.352;H 21.024 26.573 26.019;O 21.546 24.721 25.823;C 20.699 23.878 25.511
end

basis "ao basis"
  * library 6-311+g*
  bqH library H 6-311+g*
  bqO library O 6-311+g*
  bqC library C 6-311+g*
end
scf
  doublet
  direct
  maxiter 1000
end
mp2
  freeze atomic
end
bsse
 mon first 1 2
 mon second 3 4
end
task mp2 energy

But ending up with an error again saying:

 mp2_grad: unknown SCFTYPE                    0

I have tried "rhf" also, but it raised the same error.
Please provide some suggestion to resolve this issues.

Thank you.
