404 Error Page Won't Load On IE 6 and IE 7

    Wow, this surprised me, I didn't realized that ALL THE TIME my blog's 404 won't load! Geesh, that's a sucker.

    You see, I'm using wordpress (My blog is at http://www.carlocab.com ) and wordpress themes has a 404 page included. I was just wondering why this happened, it loaded in firefox but not on IE. See it for your self. try it on IE and firefox.

    The only thing that comes to my mind is that you're on a php/cgi machine and the header() format is different in cgi vs module php. Could be your 404 handler in your theme hasn't been patched for this and isn't sending the proper header for the cgi:

    Look in the 404.php file for:
      if ( !empty($error) && '404' == $error ) {
    PHP:
    if all you see is:
    @header('HTTP/1.1 404 Not Found');

    Replace it with:

     
           if ( preg_match('/cgi/', php_sapi_name()) )
     		@header('Status: 404 Not Found');
     	else
     		@header('HTTP/1.1 404 Not Found');
          }
    
    PHP:

    dont know how you are going about this but i checked the headers you are sending ..... it says
    404 OK
    which is incorrect .. IE is treating it correctly by showing its own 404 page .. try to send 200 OK instead of 404 OK

    do you see something like this in the file?

    header("HTTP/1.1 404 OK");

    if yes change 404 to 200.

    That is a strange one. If I refresh the page enough times in IE I get the correct error page, but mostly it gives the IE default 404 message. Firefox always gives the correct one.

    Here are your response headers:

    PHP:

    Notice the difference from 'OK' and 'Not Found'.

    I found this at wordpress.org
    I suggest looking in your 404.php file to look for that line, perhaps it was written wrong by your template designer or it is missing and needs to be added.
