Constantly getting a 403 error.

You don't have permission to access /index.html on this server.

Is it possible that apache cant access www group ?? How do I check / verify ??

Some leads to try following:

Regarding file permissions, the permissions of every parent directory matter too. They must all have execute permission (meaning "search" for directories).

ls -l / /home /home/eric /home/eric/cascade

To check easily, you could su to the user apache is running as and try catting the file, e.g,

sudo -u nobody cat /home/eric/cascade/public/index.html

And the group doesn't matter if the world permissions are more inclusive anyway.

Also, what's in that .htaccess file? I noticed you enabled them with AllowOverride and there's one in that directory.
