XAMPP default folder on OSX

Getting Started manual says I can put my files in /Applications/XAMPP/htdocs/ folder and in /Sites/ folder, but when I put files in /Sites folder it gives me this error:

Server error!

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

If you think this is a server error, please contact the webmaster.

Is there something that needs to be changed?

Also, when I try to restart XAMPP via Terminal I get this message:

XAMPP: Starting ProFTPD.../Applications/XAMPP/xamppfiles/xampp: line 184: /Applications/XAMPP/xamppfiles//var/proftpd/start.err: No such file or directory
fail.
Contents of "/Applications/XAMPP/xamppfiles//var/proftpd/start.err":
cat: /Applications/XAMPP/xamppfiles//var/proftpd/start.err: No such file or directory

Does this have something to do with the installation?

Thanks

You can follow these:

sudo mkdir /Applications/XAMPP/xamppfiles/var/proftpd/

sudo touch /Applications/XAMPP/xamppfiles/var/proftpd/start.err

sudo /Applications/XAMPP/xamppfiles/xampp fix_rights

have you put a file which is either index.html or index.php

if no put a index.php file in htdocs with

 <?php
    $uri= $_SERVER['HTTP_HOST'];
    header('Location: '.$uri.'/site/');
    exit;
 ?>
