Hi, I am getting a error/warning on the top of my page.

It looks like this:
[code]
Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /vservers/shopmemo/htdocs/index.php:2) in /vservers/shopmemo/htdocs/library/config.php on line 11

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /vservers/shopmemo/htdocs/index.php:2) in /vservers/shopmemo/htdocs/library/config.php on line 11[/code]

Does anyone have any suggestions on how to fix this problem? Thanks in advance.

Nick

Hi, thanks for the quick response. However I am kind of new with PHP, can you tell me what that means. Thanks in advance.

Here is what the code looks like:
[code]<head>
<style type="text/css">
.style1 {
font-family: "Bauhaus 93";
}
.style4 {
font-size: xx-large;
}
</style>
</head>

<?php
require_once 'library/config.php';
require_once 'library/category-functions.php';
require_once 'library/product-functions.php';
require_once 'library/cart-functions.php';

$_SESSION['shop_return_url'] = $_SERVER['REQUEST_URI'];

$catId  = (isset($_GET['c']) && $_GET['c'] != '1') ? $_GET['c'] : 0;
$pdId  = (isset($_GET['p']) && $_GET['p'] != '') ? $_GET['p'] : 0;

require_once 'include/header.php';
?>
[/code]

Thanks for you help, however now I am getting a notice.

[code]Notice: A session had already been started - ignoring session_start() in /vservers/shopmemo/htdocs/library/config.php on line 11[/code]

Here is what the code looks like so far.
[code]<?php
ob_start();
session_start();
?>
<head>
<style type="text/css">
.style1 {
font-family: "Bauhaus 93";
}
.style4 {

}
</style>
</head>

<?php
require_once 'library/config.php';
require_once 'library/category-functions.php';
require_once 'library/product-functions.php';
require_once 'library/cart-functions.php';

$_SESSION['shop_return_url'] = $_SERVER['REQUEST_URI'];

$catId  = (isset($_GET['c']) && $_GET['c'] != '1') ? $_GET['c'] : 0;
$pdId  = (isset($_GET['p']) && $_GET['p'] != '') ? $_GET['p'] : 0;

require_once 'include/header.php';
ob_end_flush();
?>
<table width="780" border="0" align="center" cellpadding="0" cellspacing="0" height="100%">

  <td width="164" valign="top" height="100%" background="images/index1_55.jpg"  id="leftnav">
<?php
require_once 'include/leftNav.php';
?>
[/code]

Any suggestions would be appreciated.

Move the first four require_once statements to the beginning of your script.
[code]<?php
require_once 'library/config.php';
require_once 'library/category-functions.php';
require_once 'library/product-functions.php';
require_once 'library/cart-functions.php';
?>
<head>
<style type="text/css">
.style1 {
font-family: "Bauhaus 93";
}
.style4 {
font-size: xx-large;
}
</style>
</head>

<?php

$_SESSION['shop_return_url'] = $_SERVER['REQUEST_URI'];

$catId  = (isset($_GET['c']) && $_GET['c'] != '1') ? $_GET['c'] : 0;
$pdId  = (isset($_GET['p']) && $_GET['p'] != '') ? $_GET['p'] : 0;

require_once 'include/header.php';
ob_end_flush();
?>
<table width="780" border="0" align="center" cellpadding="0" cellspacing="0" height="100%">
  <tr valign="top">
  <td width="164" valign="top" height="100%" background="images/index1_55.jpg"  id="leftnav">
<?php
require_once 'include/leftNav.php';
?>[/code]

you still need the session_start() before anything else

[code]

No, the session_start() function is inside the config.php included file. That is obvious from the error the OP posted earlier:
[quote]Notice: A session had already been started - ignoring session_start() in /vservers/shopmemo/htdocs/library/config.php on line 11[/quote]

I checked and there is nothing before the <?php. So I don't need the session_start() after the <?php? I took that out and I get the previous error again.

[code]Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /vservers/shopmemo/htdocs/index.php:1) in /vservers/shopmemo/htdocs/library/config.php on line 11

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /vservers/shopmemo/htdocs/index.php:1) in /vservers/shopmemo/htdocs/library/config.php on line 11[/code]

Here is what the code looks like on my end.
