It sounds like you may need a Directory directive that gives Apache
access to files. See 26:26 in the screencast, or make sure you have
something like this in your configuration:
<Directory "/Users/me">
Order allow,deny
Allow from all
</Directory>
You'll also need to restart Apache from the Sharing control panel.
If that doesn't work, you could try restarting from the command line
as mentioned in the Troubleshooting section.
sudo apachctl -k restart
That may show an error that could be useful in figuring out the
problem.
