When execute header("Location: new/location.php") command I got session problems.
On local host testing everything works just perfect, but if i send my project on web server hosting i got these errors:
Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /srv/disk4/2008248/www/some-url.com/new/location.php:2) in /srv/disk4/2008248/www/some-url.com/new/location.php on line 7
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /srv/disk4/2008248/www/some-url.com/new/location.php:2) in /srv/disk4/2008248/www/some-url.com/new/location.php on line 7
, so my question is how to fix this problems and keep session values alive, so i can use that values in another redirected page?
Warning: session_start(): Cannot send session cookie - headers already... a typical error when something is before session_start()
You need to write session_start() above headers(). As error says you already sent something beforee session start. Make Session start the very first line of your script, and leave no spaces before <?php tag
use ob_start(); on top of the php page

I need to access the Session in my PHP Web-Socket. I've already got the SessionID from the header but if I try to start the session, I get the Error:
PHP Warning: session_start(): Cannot send session cookie - headers
already send by (output started at ....)
I tried (https://stackoverflow.com/a/31532785/8510512):
session_id($sessionID);
session_start();

Every time I login to my cpanel, it always say connection is not private. So, what I do is to click the link on the advance option, then whenever I upload php files it always say:
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at directory file)
Even though there's no error in my code, it functions well but, the warning keeps bothering me, please help!
For the cPanel login, Please check your cPanel services SSL Certificates if you have root access, As there is an issues with the cPanel SSL and due to that you are unable to login your cPanel.
Hi I would really appreciate some help. I get the following errors at http://www.bookapartmentsinyork.co.uk/

I have tried so many thing but it's all got pretty confusing for me. I'm using GoDaddy,
The error was caused after changing from a Windows to Linux server. I am very new so please try to help me in your explanations as I may get confused easily :) Thank you!
It looks like the 'quitenicebooking' plugin is trying to read session storage data which does not exist.
The subsequent errors regarding headers already sent is just a consequence of the fact that the first error appears.
You could try changing the session storage location using ini_set().
Be sure to set session_start() at the very beginning of your file.
You're getting this error because the header are already sent.
I am trying to run this code in my server
<?php
session_start();
?>
I am getting following warning messages. I never saw such warning before .
Warning: session_start() [function.session-start]: open(/var/chroot/home/content/00/6684400/tmp/sess_uoouukt8m6efc0nc2ar5t2vq94, O_RDWR) failed: No such file or directory (2) in /home/content/00/6684400/html/html-tweetcomments/y.php on line 2

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct () in Unknown on line 0
how can i solve this problems?
Make sure, folder /var/chroot/home/content/00/6684400/tmp exists and is writable by PHP
sudo mkdir -p /var/chroot/home/content/00/6684400/tmp/
sudo chmod 1777 /var/chroot/home/content/00/6684400/tmp/
session_start() sets a cookie containing the session id. In the HTTP protocol, Cookies are sent in the HTTP header Set-Cookie.
If you send any output (including PHP warnings), this will be written into the HTTP answer body and PHP is no longer able to send a header.
To make sure the HTTP response body is written at the very end you can add a ob_start() at the very beginning of your PHP script.
This creates a output buffer which will be automatically flushed to output when the script reaches the end.

Problem with permissions.
Check tmp folder permissions. Make it writable.

Also, check there's no HTML or whitespace before session_start()

Something is being printed before your session_start call. Check for any echo or even any blank space in html, before your call
The clue is the first error:
open(/var/chroot/home/content/00/6684400/tmp/sess_uoouukt8m6efc0nc2ar5t2vq94, O_RDWR)
failed: No such file or directory (2)
It looks like the directory that is being referenced for the session files either doesn't exist or isn't writable by the web user (user as which the web server is running).
Check that the directory exists - create it if not.
Ensure that it is group writable by the web server user.
The first error is causing the rest of the errors;
If there is same output before php code, move it after the php code
Example:
<script>
...javascript code...
</script>
<?php
session_start();
?>
move the script tag after the php tag. Like this:
<?php
session_start();
?>
<script>
...javascript code...
</script>

i am getting these two warning which i was not getting on local server... why ....
See the first note on the php session_start() page. session_start() sends cookies to the browser, and the server will not send any additional data (including cookies) after any data has already been sent. This can simply be fixed by making sure that nothing is being sent to the browser (such as an echo() or var_dump() call) before calling session_start().
You don't get them on local server because you have lower errer reporting level on it. So, you need:
On you local server edit php.ini and set error_reporting to E_ALL
Move you session_start() call before line 16 of you /home/moonpk/public_html/wallz/preview.php file
Most likely you have some whitespace outside any PHP-tags in files that are loaded before the session_start() is executed. Maybe your FTP client messed things up?
You probably had warnings suppressed on your local server? The issue is that you have some output before you call session_start. Judging by the line numbers, I'd guess you have a line break before your opening php tag, but without seeing the code, can't provide a full solution.
If you are including the page "preview.php" within "loginbox.php" check that you have only called session_start once on one page.
Either on preview.php or loginbox.php , not both.
