Empty Page

Folks,


Why does my login.php show a complete blank page ?
Error reporting is set in the config.php but no errors are shown! Strange!


site_details.php

Code:

---

<?php

$site_name = "myworld";
$social_network_name = "myworld";
$site_domain = "EDITED";
$site_admin_email = "myworld_admin@EDITED";
$social_network_admin_email = "myworld_admin@EDITED";

?>

login.php

Code:

---

<?php

include 'config.php';

        //Redirect user to homepage page after 5 seconds.
        header("refresh:5;url=home.php");

Do you have error_reporting turned on? Might have an error somewhere causing it to fail.

Issue was solved, But I cannot remember how.
