Trouble with apache and CI

[eluser]peekk[/eluser]
Hi guys, i have the following problem with my CI and apache. I have all things required (i think so - installed) and when i'm trying to use any of my controllers, i see the blank page. Why is that?
(mod rewrite is enabled!)

Check for white space before the opening PHP tag and do not use the closing PHP tag.

Make sure you are not also using PHP short tags.

Make sure when you save your files that you are not saving them with the BOM.

Turn on display errors in php.ini to see what is the error message.
