Codeigniter default uri problem

[eluser]Derek Jones[/eluser]
Ok, you're experiencing both the issue of ORIG_PATH_INFO containing the full request URI and your .htaccess is changing your request for http://example.com/ into http://example.com/index.php/ (note the trailing slash). The latter is the main source of your difficulty. You'll notice that if you disable your .htaccess, then the request to your domain alone works fine.

After addressing that, you may wish to simply change your 'uri_protocol' config to REQUEST_URI for 1.6.0. CodeIgniter 1.6.1 will most likely include a change to ORIG_PATH_INFO processing that will allow you to go back to 'AUTO'. So again to summarize:

1) Your .htaccess is writing requests for the domain only to /index.php/
2) Switch to REQUEST_URI for compatibility with your server with CodeIgniter 1.6.0
