Did you try to reinstall FeynCalc (stable version) using the automatic installer to make sure that you have the latest bugfixes?
Yes
Hello,
I have just starting working with the PHI package and I am trying to compute the Feynman Rules for a 4 pions vertex. I looked to the example given in the PhD thesis of Frederik Orellana but I did not get the same result and I do not understand why. I have basically copied the commands in that example but I get a lot of errors; already when I load FeynCalc I get the message that $Configurations and $Lagrangians appears in multiple context.
I attach my notebook where my code is written to a better comprehension of the problem.
PHI bugs should be reported in the PHI repository. I do have notifications for all FeynCalc-related repos,
but I don't always have time to react within hours.
Your Mathematica version
13.0.1 for MacOS
Your FeynCalc version
9.3.1
