Use the undo button in your editor to go back to just before the simplification step that made the problem go away then examine the code you were about to remove. The trick is to remove code that is unrelated to the problem until you have distilled the code down to a small sample that demonstrates the issue. Be warned, using this technique you may end up finding the solution yourself.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
