php internal server error

If you just see a blank page instead of an error reporting and you have no server access so you can't edit php configuration files like php.ini try this:

- create a new file in which you include the faulty script:

<?php
 error_reporting(E_ALL);
 ini_set("display_errors", 1);
 include("file_with_errors.php");
?>

- execute this file instead of the faulty script file

now errors of your faulty script should be reported.
this works fine with me. hope it solves your problem as well!
