Warning: File upload error - unable to create a temporary file in Unknown on line 0

I've done some looking around to find the information to this, but haven't had much luck as most questions are people writing their own code.
I'm building a Wordpress site on Xampp. I downloaded the template files from the source site.
I go to the homepage and try to change something, press update then get the following error on a blank white page:
Notice: Unknown: file created in the system's temporary directory in
Unknown on line 0
Warning: Cannot modify header information - headers already sent in
Unknown on line 0
Warning: Cannot modify header information - headers already sent in

Warning: Cannot modify header information - headers already sent in
C:\xampp\htdocs\nashdha\wp-includes\pluggable.php on line 1219
I'm not keen to mess with the wp-includes file, but not totally sure what else to do. Any ideas?

How to fix "Headers already sent" error in PHP

After reading other similar question this is what I understand. I can set my own session_save_path() but i am on a shared host and can't set the save path above public_html. For session_start() headers alredy sent there is nothing else above my session_start() statement. The second warning says output started at 2 lines of index.php that is exactly where I have set session_start().
Here is the exact error i am getting
Warning: session_start(): open(/home/users/web/b2659/ipg.apnasikkacom/cgi-bin/tmp/sess_d48d5bfff4fc5df81ab868122feec5e3, O_RDWR) failed: No such file or directory (2) in /hermes/bosnaweb04a/b2659/ipg.apnasikkacom/8mags/bored/people/index.php on line 2

I have put session_start() at the top of my PHP file.
Here is the code
<?php
session_start();
$mysqli = new mysqli($db_hostname,$db_username,$db_password,$db_database);
and other PHP code. I am using some PHP templates like this
<?php include_once("../../templates/socialtemplate.php")?>
but all these includes are after the first section of session_start() code.

I just migrated a wordpress site from a local xampp server running on my Windows 8 PC to a cpanel hosting account which I use to host a few other sites.
Post migration the site seemed to be working well, until I tried saving a page in the wordpress admin. Upon saving, I encountered the error message shown further down the page.
I have attempted to troubleshoot to the best of my ability, including following the steps on the wordpress site for this particular error. So far, to no avail.
If I disable the nextgen gallery plugin, the problem goes away. I require the plugin to display images on the site though, so it's not a solution.
Interestingly enough, the changes do get saved, despite the error.
If anyone can help me figure out this problem I will be forever grateful!
Many thanks

2 possible reasons.
You screwed that page up, and PHP generates warnings (which you have seen), and then the warnings are printed to the browser, which prevents the headers being modified.
You saved the page with UTF-8 BOM, which is sent to browser before the header modification.
More like the 1st reason.

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 am getting two errors.
warning: session_start() [function.session-start]: open(..\Server\tmp\sess_mj3hbck8pvhpbioosqf4cu8ns2, O_RDWR) failed: No such file or directory (2) in C:\Documents and Settings\evan.YO-1EE77D2E6018\Desktop\Games\WoWPrivate server\Vampwow legit\Server\htdocs\include\common.php on line 3
And i am getting
warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\Documents and Settings\evan.YO-1EE77D2E6018\Desktop\Games\WoWPrivate server\Vampwow legit\Server\htdocs\include\common.php:3) in C:\Documents and Settings\evan.YO-1EE77D2E6018\Desktop\Games\WoWPrivate server\Vampwow legit\Server\htdocs\include\common.php on line 3
I am stumped, i dont know how to fix this and i could not find a solution anywhere
Here is my Common.php file, i will post it below.
<?php
session_start();
if (!defined('PATHROOT'))
{define('PATHROOT', './');}
Second error "headers already sent" is because you get the first error.
First error is probably you run out of disk space on your account. Check your disk space limit and increase it if possible.
EDIT:
For first error also check the question below
Warning: session_start() failed: No such file or directory
session_start(); should be the first line don't leave an empty line.

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.
