Default Controller Has Erratic Display

[eluser]Eric Cope[/eluser]
On my test server (also my workstation), a CodeIgniter Installation fails to display the default controller/view. On my production server, it displays fine. Both servers have slightly different installations, but no major differences. Any ideas why this would happen?

Do you need to define the index.php as the home page in your config.php for the local version?

What does "fails to display" actually mean? Do you get a CI 404, Apache 404, otherwise?

I get nothing. Firefox shows "done", but there is not data transfer.

You have a PHP error. Check your error logs. There must be differences in your server configurations. One might have short tags enabled, one might not. One might be a different version and you are using functions that do not exist. Run phpinfo() in both environments and find the culprit.
