    Warning: Cannot modify headerm msg

    I am getting the following error msg whenever I try to login. I tried to turn my output_bufferin g = On in my php.ini but is not working for me. Would you please help me:

    Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub ........login\i nclude\header.p hp:9) in C:\Inetpub\vhos ts\.....\httpdo cs\login\login. php on line 23

    And here is the content of the header.php page which is included in all my pages:

      Heya, nasse. Welcome to TSDN!

      You can't use the header function after you output something, which header.php does in spades.

      To get this to work, you need to move your header() statement above the line where you include header.php.

      E.g.:

      [code=php]
      header('Content-type: wacky/doodle');
      include('header .php');
      [/code]

          Thank you very much for the prompt response and the effort to resolve the problem.

          But the header() statement is also included in this header.php file and is at the top of the header.php:

              I don't see it in your code, and the warning you're getting is complaining about C:\Inetpub\vhos ts\.....\httpdo cs\login\login. php on line 23.
