Installation Issues - Nothing loads after welcome page

[eluser]bafadam[/eluser]
So, I recently acquired another domain, and am trying to get the CodeIgniter Framework installed and working. I set up the configuration with the exact same setup (except for the base URL) that my other hosting account uses.

The front page, the default controller right off the domain opens just fine. No issues there.

domain.com -> opens fine
domain.com/index.php/welcome -> does not open and gives the "No input file specified." error.

I've changed the uri_protocol setting to all of the options, and none of them worked. There is no .htaccess file in the root for me to mess with.

Anyone have any ideas on this?

Well, I don't think this is CI's fault. Maybe there's something "fancy" with the server. Error "No input file specified" could be triggered when PHP runs as CGI mode (I'm not sure about this!). You could print out phpinfo() and see if there is something not usual.
And don't forget your best friend in these kinds of situations - google.com!

A side-by-side comparison of the two phpinfo's doesn't reveal anything out of the ordinary. In fact, except for a few of the MySQL database drivers, they are identical.
