problem with my site on IIS

I run CodeIgniter apps on both a linux server and a windows IIS server.

Do you by chance have a .htaccess defined? Cause IIS doesn't do that by default. Thus 'hiding the index.php' for example won't work out of the box. That also means routing gets a bit tricky cause IIS is using it's web.config to determine what pages to load.

Explanation of the warning in detail: It cannot modify the header information cause it is outputting that PHP error. Check the PHP error logs for more info should work. Also it cannot seem to find the proper 404 page.
