Access Forbidden Error 403

Hi everyone! well I'm trying to learn ruby ​​on rails along
this tutorial:,
my controller "rails generate controller home index", edit
routes.rb uncomment the line 'root: to => "home # index"' for my
home driver is the default location when making a "localhost: 3000"
but I get an Access Forbidden! I have no permissions, error 403
Working with xampp in windows 7, and my virtualhost in httpd.conf I
<virtualHost *:3000>
ServerName rails
DocumentRoot "C:/xampp/htdocs/PFC/public"
<Directory "C:/xampp/htdocs/PFC/public/">
Options ExecCGI FollowSymLinks
AllowOverride all
Allow from all
Order allow,deny
AddHandler cgi-script .cgi
AddHandler fastcgi-script .fcgi

Before that he was in "public / index.html" that was "welcome ruby"
then to make the modification in pedia routes.rb delete this index
should work but does not work .. any help do not know why
where to look ... I'm still very new to this ... thanks!
One thing I have noticed that if I comment the line "Options ExecCGI
FollowSymLinks" ERROR 403 not out but if it shows the contents of
directory "public" and not re-routed to my new index that I created

Sorry for my bad English!
I hope you can understand!
