Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /www/ in /www/ on line 2
Unknown column 'sc_order_email' in 'field list'

[B]..i just want to know whats this problem all about my dbase connection code is this:[/B]
// database connection config
$dbHost = '';
$dbUser = '65541_jamaika24';
$dbPass = 'jamaika24';
$dbName = 'epurchasing_zymichost_dbase24';

// setting up the web root and server root for
// this shopping cart application
$thisFile = str_replace('\\', '/', __FILE__);

$webRoot  = str_replace(array($docRoot, 'library/config.php'), '', $thisFile);
$srvRoot  = str_replace('library/config.php', '', $thisFile);

define('WEB_ROOT', $webRoot);
define('SRV_ROOT', $srvRoot);

// these are the directories where we will store all
// category and product images
define('CATEGORY_IMAGE_DIR', 'images/category/');
define('PRODUCT_IMAGE_DIR',  'images/product/');

// some size limitation for the category
// and product images

// all category image width must not 
// exceed 75 pixels

// do we need to limit the product image width?
// setting this value to 'true' is recommended
define('LIMIT_PRODUCT_WIDTH',     true);

// maximum width for all product image

// the width for product thumbnail
define('THUMBNAIL_WIDTH',         75);

if (!get_magic_quotes_gpc()) {
    if (isset($_POST)) {
        foreach ($_POST as $key => $value) {
            $_POST[$key] =  trim(addslashes($value));

    if (isset($_GET)) {
        foreach ($_GET as $key => $value) {
            $_GET[$key] = trim(addslashes($value));

// since all page will require a database access
// and the common library is also used by all
// it's logical to load these library here
require_once 'database.php';
require_once 'common.php';

// get the shop configuration ( name, addres, etc ), all page need it
$shopConfig = getShopConfig();

Do you have anything, even a return character or space before the <?php or after the ?> ?

you are using plain cart. If you set up the DB along with the tutorial then there is a missing field in your SQL statement.

Solution = add the field to the shop config table or edit the SQL statement.
