You should be using $vbulletin->db... to access queries, data, and the like... try this code:

PHP Code:

<?php
global $vbulletin;

require_once('includes/class_paid_subscription.php');

$susers = $vbulletin->db->query_read_slave("
    SELECT *
    FROM " . TABLE_PREFIX . "subscriptionlog
    WHERE status = 1
    AND userid = " . $vbulletin->userinfo['userid']
);
$isPremium = $vbulletin->db->num_rows($susers);
if ($isPremium != 0){
    $st = '1';
}else{
    $st = '0';
}
    echo $st;

?>
