95% you are trying to set a cookie, mime-type or redirection (short: http header) after you have sent http body, i.e. content. Check if you you have anything including whitespaces outside the php delimeters.

If you use the header function you have to be careful... You can't send any header before the "header location".

ob_start('mypage');
    <html>
             // Your code ...
    </html>
ob_end_flush();

What's the error ? (php.ini, active the errors)

Else you can use the ob_start() function !

Cannot modify header information
