CodeIgniter's default controller doesn't load

Question

I have inherited an on-going CI v2.0.2 project.

I tried loading the default controller - http://localhost/ci202/index.php - but all I got was a blank page.

I enabled logging for all messages, and here's the log:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed'); ?>

DEBUG - 2012-10-05 23:55:41 --> Helper loaded: url_helper
DEBUG - 2012-10-05 23:55:41 --> Database Driver Class Initialized

To get this log, I only re-loaded index.php once.

The contents of routes.php & .htaccess are the same as the default installation of CI v2.0.2.

I tried creating another 'helloworld' type controller, which was a replica of the welcome controller, but still get a blank page.

Where else should I look for misconfiguration?

sounds like you are getting a white screen of death? have you tried using a completely blank installation of codeigniter on your server - confirmed that is working ok? — Laurence

@TheShiftExchange Yes, a completely new installation of CI v.2.0.2 works perfect on my machine. — Hrishikesh -Rishi- Choudhari

You should check your error log from Apache - sounds like PHP is failing and not CI. — Repox

Try to rename the index.php to something like home.php. One more thing you can do is go to /config/routes.php and change $route['default_controller'] = 'welcome'; to another controller. — manix

This may help you to find the problem.

Make sure the database connection is successful
If you enabled output compression from CI config file, disable it from config.php:

$config['compress_output'] = FALSE;
Change the default environment setting from index.php to development`, so you can see any errors that may occur in the application:

define('ENVIRONMENT', 'development');
