#1 Blank page after installation

[Miroslav Schlossberg]

Dear Developer,
After I installed Prodler and set up db, I got empty page.
I made 2 db: prodler and prodler-images

See below db.class.php excerpt:

var $sHost = 'localhost'; // Hostname of our server.
var $iDbxType = ''; // Type of database (http://www.php.net/manual/en/ref.dbx.php)
var $sDatabase = 'prodler'; // Logical database name on the server.
var $sUser = 'prodler'; // User und Password for login.
var $sPassword = 'prodler';

var $sHost = 'localhost' ;
var $iDbxType = DBX_MYSQL ;
var $sDatabase = 'prodler-images' ;
var $sUser = 'prodler' ;
var $sPassword = 'prodler' ;

var $sDateFormat = 'd-m-Y H:i:s'; //example: '2003-12-14 13:03:02'

(I've also changed date format)

Can you help me?
Why I get blank page? Is there any other config file I have to setup first?

I use XAMPP server version 1.6.8.

Thank you!
