[SOLVED]White screen instead of login page? Problem with making database connection?

[pgentoo]

I've created a test php script, which is able to connect to my db, use ispcp database, and query a table... So my php/mysql installations are working fine...

Code:

<?php
       mysql_connect("localhost", "root", "notmyrealpassword") or die("unable to connect to db");
       mysql_select_db("ispcp") or die("Unable to select ispcp database");

      $result = mysql_query("select * from admin");
      $array = mysql_fetch_array($result);
      print_r($array);
?>

this executes and shows me the contents of the admin table...

Any ideas?
