Hi there,

First of all I would recommend that you upgrade one minor version at a time. It is harder to debug issues when you are trying to upgrade multiple minor versions at a time. Right now you are trying to do these jumps:

  • Rails 3.2 → 4.0
  • Rails 4.0 → 4.1
  • Rails 4.0 → 4.2

I think that the issue you are seeing is related to the trace log level no longer being supported? See more here: Can not set trace level Rails 4 · Issue #5 · reidmorrison/rails_semantic_logger · GitHub

Maybe you can try setting the log level to :debug?
