IIS 7, PHP 5, Fresh Installation

Moved web.config up from docs/install-iis directory.

Using URL_REWRITE

My config-evrns.php

$__instances['live'] = array(
    'prefix' => 'www.myjobsxxx.com',
    'db_host' => 'localhost',
    'db_port' => 3306,
    'db_user' => 'root',
    'db_password' => 'xxxx',
    'db_name' => 'myjobsxxx',
    'db_prefix' => '',
    'app_url' => 'http://www.myjobsxxx.com/',
    'ini_error_reporting' => E_ALL,
    'ini_display_errors' => 'On',
    'location' => 'online',
    'environment' => 'prod',
    'rewrite_mode' => 'iis_url_rewrite'
);

Blank page with display_errors = 'Off'

With display_errors On, i get this:

Warning: include(C:\inetpub\wwwroot\myjobsxxx\_templates\default\_cache\%%45^45E^45E480CD%%index.tpl.php) [function.include]: failed to open stream: No such file or directory in C:\inetpub\wwwroot\myjobsxxx\_includes\smarty\libs\Smarty.class.php on line 1256

Any thoughts?
