Difficulties starting codeIgniter

[eluser]windlessuser[/eluser]
Hey, I was introduced to codeIgniter thought NetTuts. I using the framework to speed up dev time on a job board/class fields site I'm making. I was using some code i found on Nettuts, that gave a base of what i wanted to do, and was going to extend that. However when i start CI fresh, i get the welcome screen. However, when i change anything...nothing comes not, not even an error. I'm running CI on my local machine. It's running apache 2.2 with php 5.3 I know my installation works cause I get feed back with phpinfo(); Any idea of whats wrong. I know the nettuts code works...for them atleast.. Please help!

changes made from default setup:

in /config/config.php: $config['base_url'] = 'http://localhost/jobs-tut/';
$config['global_xss_filtering'] = TRUE;

in /config/database.php, i set my databse info up, also on the local machine.

in /config/autoload.php: $autoload['libraries'] = array('database', 'form_validation');
$autoload['helper'] = array('url','form','security');

in /config/routes.php: $route['default_controller'] = "jobs";

in /controllers/, there is a controler jobs.php:

<?php

class Jobs extends Controller {

function Jobs() {
parent::Controller();
$data['sitetitle'] = 'Job Board';
$this->load->vars($data);
}

function index() {
redirect('jobs/listings');
}

function listings() {
echo 'hello world';
}

}
# End of file 'controllers/jobs.php'

Now even with all of that, The url "http://localhost/job-tuts/index.php/jobs/listings" (without quotes) but nothing is returned...Not even an error

Help!

I tried an existing codeIgnither app, namely bambooInvoice...It doesnt work either. I was thinking the issue was with with my apache/php installation, but then i tried it with XAMPP, but im getting the same issue... What could be wrong guys?

If you get a blank screen, your errors are probably going to apache error log so check that or set display_errors to on(and also check the error_reporting level). Also check CI logs from system/logs.

No need to add closing php tag and its preferable to leave it off.

UPDATE:

localised the issue, to be a database one. Not sure why though, MySQL process is running. and my php and apache are configured for it. And no errors are being thrown or logged. Help!
