On the XAMPP everything working fine.
Today i uploaded my website on hosting (000webho....)
When I try log-in i got like this:
Cannot modify header information - headers already sent by (output started at /storage/ssd3/390/15429390/public_html/zaloguj.php:10) in /storage/ssd3/390/15429390/public_html/zaloguj.php on line 79
Line 10 in zaloguj.php: else if ( ($_SESSION['zalogowany']==true) && ($_SESSION['stanowisko']=="xyz"))
Line 79 in zaloguj.php: header('Location: index.php');
What's wrong?
Add this line in .htaccess:
php_flag output_buffering on

I have some issues in my application, I uploaded it to a domain server and have this ERROR here:
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/emavula/public_html/deco.co.mz/store/login_admin.php:1) in /home/emavula/public_html/deco.co.mz/store/funcoes/funcoes.php on line 4
It sounds like some output was sent in /home/emavula/public_html/deco.co.mz/store/login_admin.php:1. Because it is on line 1, I strongly suspect a new line or space before <?php. If it isn't that, maybe check the error log and make sure the log level is set to at least warning.

I made an index.php file with this require:
require 'Model\Db.php';
require 'Model\User.php';
require 'Model\Collection\UserCollection.php';
require 'View\ListView.php';
require 'View\FormView.php';
require 'View\MenuView.php';
require 'Controller\Controller.php';
on my laptop there are no problem but on the server it doesn't work. I don't have any warning (and I don't know how to activate them on server), I think is require fault because code after them are not executed.
In my log report I have:
PHP Warning: Cannot modify header information - headers already sent by (output started at /home/svyshloc/public_html/Esome/index.php:15) in /home/svyshloc/public_html/Esome/index.php on line 44
and code bugged is this:
if (($setting_page['basename'] == "Esome")) {
header("location: index.php?page=home");
} else {
$page = $url['page'];
}
Check your servers error logs. I've had same problem before with iPage servers but it got solved after I saw the real error from the servers logs.

I dont know why I'm having this error:
Warning: session_start(): Cannot send session cache limiter - headers
already sent (output started at
/home/jogarspy/public_html/index.php:2) in
/home/jogarspy/public_html/core/init.php on line 3
In my init.php there are just one session_start();
How can I fix it?
Starting a session sends a cookie to the browser. This is in the HTTP header. Therefore do it before sending any other output as this will tell the web server the headers are good to go.
session_start() needs to be on the very first line of the file.
Look at "Starting a PHP Session"

My site is running fine on one server but when I shifted it to another server, some pages are giving following warning message.
Warning: Cannot modify header information - headers already sent by (output started at /home/parviz/public_html/ganj_videos/lang/english.php:1) in /home/parviz/public_html/ganj_videos/mobile/detect.php on line 50
Any idea on how to fix it?
Thanks.
Most likely your new server has a different setting for the errors and warnings. If PHP issues a warning or error as output then it will cause your headers to fail.
Change the level using the error_reporting function.
Just follow the debug: it says output started in file /home/parviz/public_html/ganj_videos/lang/english.php on line 1. There's most probably some messy newlines or spaces there. Make sure all php files executed start with <?php and NOTHING else before it, or you'll get the warning.

I have created a dynamic menu CMS website. I developed in a Windows system. When i run my project in windows operating system, My project runs without any error. But now uploaded it into Linux Operating system server i am getting warning & error like:
A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/ansofcm8/public_html/apps/resources/math/application/core/MY_Controller.php:1)
Filename: libraries/Session.php
Line Number: 675
What could be the reason. Please help me.
There seems to be whitespace before the php open tag <?php in MY_Controller.php.
Check all PHP files and remove the whitespace before the <?php tag. If there is a space or new line, the body of the http request is started, and you can't add new headers to the http request.
