You need to set a bigger number to really shut up Minuit2 :-)

If you want it REALLY quiet, try

gErrorIgnoreLevel = kFatal;

Take a look at the logic in the root source where it uses the value of gErrorIgnoreLevel: base/inc/TError.cxx and base/inc/TError.h

This logic is the same in both 5.14 and 5.18, so I would imagine the above approach should work in either case.

But you might really want to explore _why_ your minimizations are failing in the first place, rather than just silencing them ... they're telling you something is very wrong. I just spent a week doing exactly that, and it turned out my problems were much bigger than Minuit2 making lots of noise....
