Whenever i click on the attachments i get error 404 Not found, nginx/0.7.17.
Even the avatar are not displayed.This problem has raised out of nowhere and suddenly. I was nothing doing in my admin panel nor in ftp.

This is how error page looks like...

Anyone, help please. How do i fix the problem.
