I can't see the server name being referenced, since it IS executing your index.php and looking for a file in application/core, which means your config settings are being read. That means your paths are ok, not referenced to the original server.
The system file in system/core/Codeigniter.php is where CI loads your extended controller and it needs the app path (APPPATH) set in your index.php file. All of which works, but the actual file is not found, even though you can see it there.
It keeps coming back to either the incorrect spelling of filenames, wrong permissions or invalid user.
If the class declaration is misspelled or the filename itself is wrong, I can see the error in the apache error log. I can duplicate it by renaming my own base controller or setting the permissions to disallow reading. You are using root as the user, which should have all priviledges.
I know, it is frustrating me too...
