Dear CP2K Users, 
I was wondering if you could help me with something
i am using the CP2K 7.1 version , I am trying to do TDDFT calculations. 
however I get this error

However in my input i am not considering the PBE HOLE functional and I have 
included the derivatives.  I.was wondering if this is an issue of the 
version 7?


best.
