URGENT: Help needed modifying homepage for client

[eluser]Unknown[/eluser]
I am working on an SEO project for a client and need to make on-page modifciations to his website (which is running Code Igniter in Godaddy). However his developer has falllen off the face of the world, and I have no idea how to use Code Igniter..

I am seeing his Applications Folder > Views > and all the internal pages. However i have no idea how to make changes to his home page content. I have checked his config.php file and it appears to be referecing a databae that does't exist, there are multiple index.html files in every directory all point to ERROR 403 DIRECT NOT FOUND, I am beyond frustrated right now and could use help or would just like to hire someone to fix this issue for me so we can move forward with his campaign.

Thanks a lot in advance!
