I edited this question today to provide some context for things I've tried but it was still closed. Is this because the original poster posed the question too simply or is it still in a state to be considered off topic? I'm very new to posing questions on this SE site and the other questions about on or off topic questions don't seem to rule this question out as off topic.
If a question which is on hold is edited, then the edit pushes it into reopen review queue, assuming some conditions are fulfilled. Details can be found in this answer on our meta and this answer on meta.SO. Probably the main things are:
- This only happens if the question has been on-hold/closed for no longer than five days.
- A question can be enqueued via editing only once per closure. (So it is better to make substantial edits which address all issues which may be among reasons why the question was put on hold.
In the review, users with sufficient reputation can vote whether the question should remain closed or be reopened. After the review is finished, you can see it on the timeline of the post.
