"Missing critical ForceField parameters!" ... but which ones?

[Guillaume]

Hello,

I get this message from subroutine "force_field_pack":

*** Missing critical ForceField parameters! Abort.. ***

How do I get to find which parameters are missing?  What's a little
surprising is that the PSF file I'm reading was working fine a few
months ago (with an older version of CP2K).  I've tried adding
&FORCE_EVAL &MM &PRINT &FF_INFO, but it doesn't print anything before
the crash.

Thanks.
Guillaume
