if you post in the night is very likely no one will read it or be up to reply, this forum is visited by people around the world, but mostly visited and assisted by people in america, so if you post at 11 or 12 pm, possibly no one will see it
also, sometimes a question is weird, hard to understand or no one knows the answer, so if someone reads it but can't help, well, you get no replies
now, what is the link of your thread with no replies?
