Hi, I know this is and old problem, but I can't resolve.

Here is the Warning:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /homepages/htdocs/site/contactprocessor.php:2) in /homepages/htdocs/site/contactprocessor.php on line 6

This is my code:

<?php

$where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));

session_start();
if( ($_SESSION['security_code']==$_POST['security_code']) && (!empty($_POST['security_code'])) ) { 
mail("[e-mail]","From site","Form data:

Requirement: " . $_POST['field_1'] . " 
Name: " . $_POST['field_2'] . " 
Phone: " . $_POST['field_3'] . " 
City: " . $_POST['field_4'] . " 
Email: " . $_POST['field_5'] . " 
Comment: 
" . $_POST['field_6'], "From: $field_2 <$field_5>");

include("confirm.html");
}
else {
echo "<h3>Invalid Captcha String.  Please Input It Again.</h3><br /> <FORM> 
<INPUT type=\"button\" value=\"Go Back\" onClick=\"history.back()\"> 
</FORM> ";

}

?>

I really don't now were is the problem. Please if somebody can help me I will appreciate. Thanks.

Welcome to PHPBuilder, micbalam! Note that I've moved your post into its own thread; please don't hijack others' threads to discuss your own issues. Also, please use the board's [noparse]

..

[/noparse] bbcode tags as they make your code much easier to read and analyze.

As for your issue, the error message suggests that the session_start() call is on line #6, meaning there must be a blank line in your PHP script before the first opening "<?php" tag. Note that [man]session_start/man must come before any output - including any whitespace before the first opening tag.
