I'd guess the down votes you are getting are because of the commented out use warnings and maybe because you haven't applied due diligence in working out for yourself why you are getting warnings.

Just changing stuff at random without understanding, or at least a plan, is not the way to fix programming issues with any confidence at all that you've fixed the root issue. It's often easy to fix symptoms, but as you have found, that often doesn't have much to do with the bigger problem.

Anyway, don't worry too much about the down votes (if you were), but take them as a hint that you should think a little longer about "why?".
