Error when adding resources params for connection to database

Question

I'm adding this to application.ini into section production

resources.db.adapter           = "pdo_mysql"
resources.db.params.dbname     = "rzeki"
resources.db.params.host       = "localhost"
resources.db.params.username   = "root"
resources.db.params.password   = ""
resources.db.params.charset    = "utf8"

but when i'm running aplication I've got this error:

    Stack trace:
#0 C:\Program Files\Zend\ZendServer\share\ZendFramework\library\Zend\Config\Ini.php(296): Zend_Config_Ini->_processKey(Array, 'params.dbname', 'rzeki')

I'm using Netbeans + ZendServer CE

Edit:

When I'm installing digitalous, main index.php in install folder :
