Getting a blank page

Hi All.

I am a noob at CI, have now worked my way fixing all errors etc, got my "hello world" to work, so th CI is there and working. and off course the index.php file is loading honkey-dori

My problem seems to be DB connection, or I am not sure.....

been testing with the examples from formget.com

insert-data-into-database-using-codeigniter
update-data-in-database-using-codeigniter
delete-data-from-database-using-codeigniter

At first i got some errors, that i fixed, but now when i go to display page (for the above mentioned)
localhost/myDir/index.php/..........

i only get a blank white page, the title is loaded as i can see the text at the top.....  but nothing else
checked and added database to autoload...

i am using CodeIgniter-2.2.0
         PHP 5.63
       MySQL 5  (SQLi)

Any suggestions on how to get it to work........
