Generally, this occurs when you attempt to use header(), setcookie() or session_start() after output is sent to the client (browser). Typically, the best solution is to structure your code such that these functions are called before output is sent to the client. "Output" means anything that is printed, be it from an echo, or embedded HTML, including blank lines.

i dont understand, do you mean that i should move session_start(); and ob_start(); to an another place in the code..

Check for a space in the beginning of the file. Or, if the file is saved in a Unicode encoding, make sure the BOM marker isn't there.
