Bone Heat Weighting: failed to find solution for one or more bones

I tryed to improve the placement of the bones in my atempt to rigify a catgirl and now blender send me this error message “Bone Heat Weighting: failed to find solution for one or more bones” When I try to auto weight paint the body.

It worked fine before I haded some bones and moved other so I guessed the new ones were the reason but removing them dont help. Then I tryed to put a makehuman body instead. I had to move or remove bones to match the model ( cat ears and tail wont fit O_o) and it worked again. So I tryed again to get the skeleton work on the catgirl but without success. I tryed to google the error message but the solution I found make no real sens since the skeleton worked with other placement of the bones and they all give solution on the body you try to weight paint ( I tryed them however just in case but without success.)

Any idea?

I’m having this same issue. I went through the checklist but the error remains the same. :confused:
