auto-kick from group after X day without activity ?

[The Ottoman]

So I've saved this code:

PHP Code:

<?php 
error_reporting(E_ALL & ~E_NOTICE); 

if (!is_object($DB_site)) 
{ 
    exit; 
} 

$DB_site->query("UPDATE " . TABLE_PREFIX . "user SET usergroupid = 2 WHERE usergroupid = 15 AND lastpost < " . 

(TIMENOW-45*86400)); 

log_cron_action('Inactive VIP Users reset to Registered', $nextitem); 
?>

to a file called autokick.php, created a cron job, set it to log, and ran it manually, I just get a screen with the cron job name, and it just hangs.


I'm a tard, what am I doing wrong?
