Cannot modify header - AJAX - El Forum - 05-26-2010

Hello,
Having a problem with cookie..
I am using AJAX to run some php script that sets cookie and display a "cart" on the screen. Getting error:
Quote:A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /customers/khushimat.pl/khushimat.pl/httpd.www/system/application/controllers/ajax.php:1)
Filename: helpers/cookie_helper.php
Line Number: 92
I tried to find whitespaces and any output. Also saved the file in different editor to make sure there are is no BOM problem. Have updated cookie_helper.php file with a fresh clean copy to make sure there were now changes made. And nothing...
Any help please?

As it says that the output started at line 1 I would double check /customers/khushimat.pl/khushimat.pl/httpd.www/system/application/controllers/ajax.php:1 for whitespace before the <?php tag
If you still can't find it you should try something like firebug to look at the http traffic and see what exactly CI is sending to your browser

Hmm... actually I just manage to fix the problem using one of the previous version of the file..... but still do not know what was the problem.
Where would I look for it in fireBug?

In the "net" tab you can examine any request made by your browser; you can look in the request response to search for strange output before the html.
I'm telling you this because I had the same problem and while looking at the response I noticed that there was a whitespace before the <!DOCTYPE tag
