Blank page after autoloading database

[eluser]Unknown[/eluser]
I am new to CI. I started the configuration today, The system is working fine until I made the following change in autoload.php. After this only a blank screen loads.

$autoload['libraries'] = array('database');


any idea on where I am going wrong?

Did you create a database and configured the credentials correclty in application/config/database.php?
Check also once system/logs.

I'm having to same problem, very strange. When autoloading 'any' classes, i just get a blank screen. My log level is set the highest possible but nothing unusual seems to appear in the logs...

Any suggestions?

What is your PHP and CI version?

First problem had todo with my fresh install of xampp which comes with PHP 5.3. This caused set_date_timezone errors because php from now on requires you to explicitly set the timezone. So i included this after the error_reporting line in the index.php file.

Second xampp doesn't enable mysqli by default and/or was not able to get the right setting out of the box. After trying some tweaking of the php.ini files I uninstalling xampp and went back to an older version, on which CI runs fine now. I initially lost to much time to really dig into it...
