I posted a question on Superuser a couple of days ago and have had no answers in response - a few comments yes, but no answers. I have found out what was causing the issue I am having, but not how to overcome/fix it.
The question is now eligible for a bounty and I am very keen to get an answer.
I am unsure whether it is acceptable to edit the original question and effectively change the question from
What is causing problem X?
How do I fix problem X?
now that I have more information (effectively creating a more informative and constructive question). I personally don't see it as an issue to edit the original question as I have had no answers, so there is no chance of me invalidating any existing responses.
