setting project on Ubuntu 8.04

[eluser]Yogesh[/eluser]
I have set the permission to the folders /var , /var/www and /var/www/springboard (springboard is the project directory) from root user and it shows permission in user login as the create and delete the file in this folder . I also have share the folder /var/www from properties share tab but it did't ask any thing after I click share button but it shows the same error as it shows before is there ant issue of apache configuration setting.
Also one more important thing i forgot to mentioned is
Project also not running from the Root user login gives the same error

I have run the following command
sudo a2enmod rewriteD
sudo a2enmod userdir

but still it shows the same error
