Dear All,

I try to calculate phonon at gamma with input_dft='sla+pw+b88x+vdw1'. The scf 
calculation goes smoothly, but an error appeared in the phonon calculation. 
Below is the error message:


% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #        28
     from set_dft_from_name : error 
#         1
     NO SHORTNAME: unrecognized dft
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

   task #        
2     from set_dft_from_name : error 
#         1
     NO SHORTNAME: unrecognized dft
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The input files are shown below. Please give me some idea to remove this error.
