The terminology in that close reason can be confusing since it's covering a few different scenarios:
off-topic → Questions describing a problem that can't be reproduced and seemingly went away on its own (or went away when a typo was fixed) are off-topic as they are unlikely to help future readers.
The question as it was previously phrased was off-topic, in the sense that it was not reproducible for a variety of reasons.
- Users here do not have access to your hosting provider's environment
- The question lacked enough details to be answerable
So myself and others selected this close reason since it was the one that matched closely with the situation as it stood at that time. You've since provided more details per feedback from @frostschutz, which has improved things.
One of the primary functions of closing a question is to block it from eliciting many partial answers which are attempting to answer a question which hasn't been asked with enough specificity.
If you read through what makes a good question these 2 bullets are pretty crucial:
If you ask a vague question, you’ll get a vague answer. But if you give us details and context, we can provide a useful answer.
Make it relevant to others
We like to help as many people at a time as we can. Make it clear how your question is relevant to more people than just you, and more of us will be interested in your question and willing to look into it.
NOTE: I've personally never cared for the term "close" on questions since it has a negative connotation. Comments and closing are however, the 2 primary methods users have with interacting with the questions posted on the site.
Hopefully this makes a bit more sense to you and welcome to U&L. Hopefully you'll not take this as a negative experience. Everyone here is generally eager to help and there can be a bit of a learning curve if you're new to the StackExchange sites.
We appreciate you taking the time to read through the help (this is one of the biggest frustrations to older users of the site 8-)). Hopefully you've gained insight into why you were having your particular problem, and how the site as a whole, functions.
