   Dear ABINIT Users, I can't do optimization of the lattice parameter LaMnO3
Help me to know problems! Please send me the same input if you can.
Here is my input:

# Crystalline LaMnO3 : optimization of the lattice parameter
#
# Convergence with respect to k points.

getwfk -1

#Definition of occupation numbers
occopt 1
tsmear 0.05

#Definition of the k-point grids
kptopt 1          # Option for the automatic generation of k points, taking
                  # into account the symmetry
nshiftk 1
shiftk  0.5 0.5 0.5  # These shifts will be the same for all grids

#Definition of the atom types
ntypat 3          # There is only one type of atom
znucl 57 25 8           # The keyword "znucl" refers to the atomic number of

                  # possible type(s) of atom. The pseudopotential(s) 
                  # mentioned in the "files" file must correspond
                  # to the type(s) of atom. Here, the only type is Silicon.
