title: How do I debug issues that I can't reproduce on my dev system?
body: <p>I have recently finished phase 1 of my Facebook game:</p>

  <p>It works fine on my dev system, but other people report errors and timeouts when they try to run it. Does anyone know how I would go about debugging these issues if they don't occur on my system?</p>
  
  <p>Thanks.</p>
