[support] Setting an error page.

[Eric Sepich]

I am trying to set a custom error page. My first attempt was to use the 
administration menu and navigate to configuration->site information. 
There is a box where I can enter a URL for a 403 & 404 error page and it 
starts me with a static string http://www.sepsserver.com/drupal/. So I 
created a file here http://www.sepsserver.com/error.html and set the 
proper permissions for it like this: chmod 774 error.html. Now I set my 
403 & 404 error to navigate to 
http://www.sepsserver.com/drupal/error.html and I get an error:

The file error.html does not exist or you do not have permission to 
access it.

Well that's crap. There is a file and I do have permissions set to 
access it. In addition I have also tried using a node which does not 
work either because my anonymous users do not have permissions to view 
content which is exactly what I want.
