title: Restore Current sites-available File
body: <p>My team was trying to update nginx config, <code>sites-available/mysite.com</code>, when he was trying to save it suddenly the file can not be saved, due to the disk size problem and now the file is empty (size is 0). Is there any way to create a new config file based on current nginx conf? The nginx server haven't restarted yet since the file is edited, hence, it still works fine and we don't have the latest backup of <code>sites-available/mysite.com</code> file, thus I prefer to restore current config which exist in the memory.</p>
  
  <p>Thank you.</p>
