lamp phpmyadim working clean install on ubuntu 8.04 CI won't load welcome page

[eluser]edziffel[/eluser]
First let me apologize for the beginner junk, and although everything works great in about 40 minutes on a windows platform to include the wamp install, getting this apache install up and working is driving me up a wall. Been on it for 3 days had it once but on a splatter guess and go so reformatted and documented step by step through getting phpmyadmin running but cannot get CodeIgniter going. Would really appricate some knowelagable help as to what I'm missing.

Thanks

Ed
