[quote author="NeoAvatar" date="1242409182"]Some of CodeIgniter Core files are in UTF-8 encoding. Covert all of your (and CI) files to UTF-8 without BOM, like m3rLinEz says...Notepad++ come in hand, at all. The people that uses Dreamweaver, for example, can get some problems with encoding. Then, convert all files before the tests or deployment.[/quote]
Ya, This is a good point! make sure u this b4 u start ur development!

This error is commonly seen in PHP installations. There are multiple ways to remove this warning other than turning error reporting off.
You can turn output buffering on, use ob_ functions etc.
For a comprehensive list see Solve cannot modify header information

Be careful with output buffering. Be aware of flushes because that will still cause errors when you try to send headers.

Actually Some of the Hosts they Use the PHP Header Function to Redirect our Site! So In those kind of servers if we use redirect() it will give the error, Because the redirect() function use 'PHP header' to redirect url, So the Best Way is use javascript '[removed].href=""' to load Your URL.
100% it will be work
Example:
//Your Code in Redirect
redirect('site/function1');
//Alternate Code
$url = 'site/function1'
echo'
[removed]
[removed].href = "'.base_url().'index.php?/'.$url.'";
[removed]
';
I am not sure its a right code! But I am using it for solve the Issue!
Thanking You!

My problem was solved, removing the white space before the php opening tag.
