In an attempt to follow the example how to override a function in custom.lua, but when I run "liveconfig --diag" I get the error as indicated in the subject. All I do is include a minimally changed function LC.postfix.configure(cfg, opts).
The same method of overriding worked with another function ( LC.users.addUser). What am i doing wrong here? In what is LC.postfix.configure different that it should fail?
