Problem in Grompp with Verlet

GROMACS version: 5.0.2
GROMACS modification: No
Here post your question Hello Dear Gromacs users: I want to run an equilibration using grompp, but i have the following error: With Verlet lists coulomb!=rvdw is not supported (except for coulomb>rvdw with PME electrostatics). Could you help me please? My mdp is the following:

integrator = md

dt = 0.02

nsteps = 500000

nstxout = 0

nstvout = 0

nstfout = 0

nstlog = 1000

nstxout-compressed = 1000

compressed-x-precision = 100

cutoff-scheme = Verlet

nstlist = 20

ns_type = grid

pbc = xyz

verlet-buffer-tolerance = 0.005

coulombtype = reaction-field

crcoulomb = 1.1

epsilon_r = 15 ; 2.5 (with polarizable water)

epsilon_rf = 0

vdw_type = cutoff

vdw-modifier = Potential-shift-verlet

rvdw = 1.1

tcoupl = v-rescale

tc-grps = System

tau_t = 1.0

ref_t = 310

gen-vel = yes

gen-temp = 310

Pcoupl = berendsen

Pcoupltype = semiisotropic

tau-p = 4.0

compressibility = 4.5e-5 4.5e-5

ref-p = 1.0 1.0

crcoulomb is not a valid keyword, so grompp falls back to the default value of 1.0 for rcoulomb, triggering the warning because rvdw is set to 1.1.
