[29-Jul-2012 09:11:26 UTC] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/content/57/9417657/html/includes/languages/english/modules/shipping/flat.php:57) in /home/content/57/9417657/html/includes/functions/functions_general.php on line 45

That file doesn't have 57 lines, so when you edited it you or your editor added an extra character or line to the bottom of the file. Remove that and all will be well.

the flat.php is below. that why line 57 is... does someone the errer reson?

//define('MODULE_SHIPPING_FLAT_TEXT_TITLE', 'Delivery');

//define('MODULE_SHIPPING_FLAT_TEXT_DESCRIPTION', 'Delivery');

//define('MODULE_SHIPPING_FLAT_TEXT_WAY', 'Delivery');

define('MODULE_SHIPPING_FLAT_TEXT_TITLE', 'Flat Rate');
define('MODULE_SHIPPING_FLAT_TEXT_DESCRIPTION', 'Flat Rate');
define('MODULE_SHIPPING_FLAT_TEXT_WAY', 'Best Way')

You're looking at the wrong file. The error log is pointing to includes/languages/english/modules/shipping/flat.php, not includes/modules/shipping/flat.php.

i am sure the flat.php file is below. i am correctly looking at the file

includes/languages/english/modules/shipping/flat.php

//define('MODULE_SHIPPING_FLAT_TEXT_TITLE', 'Delivery');

//define('MODULE_SHIPPING_FLAT_TEXT_DESCRIPTION', 'Delivery');

//define('MODULE_SHIPPING_FLAT_TEXT_WAY', 'Delivery');

define('MODULE_SHIPPING_FLAT_TEXT_TITLE', 'Flat Rate');
define('MODULE_SHIPPING_FLAT_TEXT_DESCRIPTION', 'Flat Rate');
define('MODULE_SHIPPING_FLAT_TEXT_WAY', 'Best Way')

and the includes/modules/shipping/flat.php is

class flat {

var $code, $title, $description, $icon, $enabled;

// class constructor

function flat() {

  global $order, $db;



  $this->code = 'flat';

  $this->title = MODULE_SHIPPING_FLAT_TEXT_TITLE;

  $this->description = MODULE_SHIPPING_FLAT_TEXT_DESCRIPTION;

  $this->sort_order = MODULE_SHIPPING_FLAT_SORT_ORDER;

  $this->icon = '';

  $this->tax_class = MODULE_SHIPPING_FLAT_TAX_CLASS;

  $this->tax_basis = MODULE_SHIPPING_FLAT_TAX_BASIS;

it has sucessfuly worked before adding zen cart modues as minimum order and store open but the problem is after installing it..
now i remove the modues but still have a problem...

It looks like you have somehow copied the flat.php file from includes/modules/shipping into includes/languages/english/modules/shipping.

Try replacing that with the proper file from a fresh copy of the Zencart installation zip file.
