If your home directory location has been changed from the default location, your Personal Web Sharing content may not be accessible to others.
Note: If this issue occurs under different circumstances (the user's Home has not been relocated), follow the steps in Mac OS X 10.5: Web Sharing - "Forbidden 403" message appears instead of website content.
To resolve this issue, edit the user account's Web Sharing configuration file to point at the correct location of your Home. In the following instructions, replace "myname" with your username (this is the same name as your user's Home folder in the Users folder.)
You should now be able to access your website content as expected.
