Warning: Cannot modify header information - HELP!!!

My site was working fine and now all of the sudden i get this error message:

Warning: Cannot modify header information - headers already sent by (output started at /home/mysite/public_html/dirx/dirxx/dirxxx/header.php:14) in /home/mysite/public_html/dirx/dirx/dirxxx/file.php on line 41

I googled the error and got something about blank spaces but can't find anything, i made sure all the blank spaces were gone and still the error.

Anyone know how to fix it?

 

The error is not just blank spaces... it's any output (so a PHP echo / print, an HTML tag, a blank space or even a new line).

Essentially, as the error says, header.php on line 14 has outputted something. Now that may be because you printed something to the browser, or it could be because you put a new line after the closing tag.

 

I have a backup of the site on a different server and it works there so i ftp the working ones to the server where it stopped working and it still doesnt work? why would it work on one server and not on the other. Permissions are set the same.

 

post the code so someone could tell you how to fix it

 

Ok i replacted the .php file with the original that works on my other server. Here is the file. without doing any mods it throws an error message saying line 45

 

You have all this output:

<?php
include "header.php";
?>

<table width="750">
<tr>
<td width="375" valign="top">
<center>
<img src=/images/image.gif"><br><Br>

Code (markup):

and then after that you're trying to send a cookie. Cookies are send in headers, hence the error message.

I'd assume the difference between hosts is not down to the code working or not as it won't work in any case, it'll simply be one is setup to display errors and the other isn't.

Move the output so that it comes after the cookie has been set.

<?php

require './include.php';
$Score = 0;
// End of Vars! //

* ***********COOKIE STUFF!**************
* What this will do is first check to see
* if there is a cookie that has data in
* it. Next if there is no cookie we then
* calc the score and enter that data into
* the cookie.
*/
$i = unserialize($_COOKIE['Quest']); //Unserialize the data in the cookie (if there is one) and put the array in the var "$i"
if ($i[TotalScore]) { // If there is a data from the cooke do this...
$TotalScore = $i[TotalScore]; //Put data from the score in the cookie
$CookieData = serialize(array ("QuizID" => $QuizID, "Taken" => "Yes", "TotalScore" => $TotalScore)); //Load up the data!
setcookie("Quest", $CookieData, time() + 60 * 60 * 24 * 30); //Bake the cookie!
} else {
// This will clac the score..
foreach($Quiz as $Question) {
// This is a quite verison of the answer checker as show above...
$QuestionArray++;
$Var = "Q" . $QuestionArray;
// This var is for the ammount of questions this will be used to calc the grade
$QuestionAmt = $QuestionAmt + 1;
if (stripslashes($$Var) == stripslashes($Quiz[$QuestionArray]['Answer'])) {
$Score = $Score + 1;
}
}
$TotalScore = round($Score / $QuestionAmt * 100); // Calc the score and round it
$CookieData = serialize(array ("QuizID" => $QuizID, "Taken" => "Yes", "TotalScore" => $TotalScore)); //Cookie data

PHP:

 

Thanks that got rid of the error but now the calculation always shows as zero.

 

Is it possible that my host might of updated something on the server? different version of php? anything? how in the world does a code that has been running for months work fine and now all of the sudden not work.

 

stab in the dark, on the very first line in add

ob_start();

PHP:

???

EDIT: that is on the original version that used to work ...

EDIT2 : Actually it's not a stab in the dark, the reason is some hosts have output buffering on by default, which would explain why you got away with doing the cookie after html becuase nothin is sent to the browser untill the script has completing executing, and by this time the cookie is set and everything else is already done .... fingers crossed ....
