title: WARNING: File "/xmlrpc.php" is not readable - any ideas what to do here?
body: <p>I have a WordPress installation and I use a plugin called Backup Wordpress, which - backs up WordPress!</p>
  
  <p>So - the other day I received an error that said:</p>
  
  <p>WARNING: File "path-to/xmlrpc.php" is not readable</p>
  
  <p>any ideas what this is and how to fix it? I guess I can go into the relevant directory and FTP and change the file permissions - but is that wise for this file?</p>
  
  <p>thanks</p>
