Apache2 virtualhost 403 forbidden?

Question

I'm running ubuntu 13.04 64bit on my desktop, I installed Apache2, MySQL and PHP etc.

I wanted to have my web root in /home/afflicto/public_html instead of /var/www. So I went along with this guide:
http://www.maketecheasier.com/install-and-configure-apache-in-ubuntu/2011/03/09
(I did everything from "configuring different sites") as I like the solution more.

Here's what I did:
Installed Apache2, MySQL etc..
copied /etc/apache2/sites-avaliable/default to /etc/apache2/sites-available/afflicto. Then edited it, it now looks like the following:

/etc/apache2/sites-available/afflicto

<VirtualHost *:80>
ServerAdmin webmaster@localhost

DocumentRoot /home/afflicto/public_html
<Directory />
    Options FollowSymLinks
    AllowOverride None
</Directory>
<Directory /home/afflicto/public_html/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    allow from all
</Directory>

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
    AllowOverride None
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    Order allow,deny
    Allow from all
</Directory>

ErrorLog ${APACHE_LOG_DIR}/error.log

# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn

CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>  

I did sudo a2dissite default && sudo a2ensite afflicto && sudo service apache2 restart

I created a index.php and index.html in /home/afflicto/public_html/test/
when accessing localhost/test or localhost/test/index.html etc, I get 403 forbidden error.

What am I doing wrong?

update 1
I have set the owner of the public_html directory to www-data.
Also sudo chmod -R +x public_html && sudo chmod -R 777 public_html
Still same 403 error.

Here's the output of the apache error log:

[Sun Jul 14 06:10:32 2013] [error] [client 127.0.0.1] (13)Permission denied: access to / denied

[Sun Jul 14 06:10:32 2013] [error] [client 127.0.0.1] (13)Permission denied: access to /favicon.ico denied

Answer 1

Turns out I had to chmod not only /home/afflicto/public_html but also /home/afflicto/ directory as well.

Weird.
