Dear QE Fellows,I am trying to apply LDA+U+SOC Scheme on Mn-doped silicon system (Magnetism is also incorporated). I am using version espresso-5.0.2. After running till first scf cycle (couple of iterations), when it comes to write the forces acting and coordinates of relaxed system, the calculation is crashed with the following error: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine force_hub (1):
      forces in full LDA+U scheme are not yet implemented
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

     stopping ...

.......

Can somebody check the input and suggest some solution? 

Thank you in advance. Below is the input:
