Warning: Cannot modify header information.

[samer]

ok, here's the thing:
i'm creating some kind of 'external phpbb mod', it's a menu, on my homepage that changes depending if you're online or not.
everything is working now, except that i'm getting this error, on top of the menu:

Warning: Cannot modify header information - headers already sent by (output started at http://www.url.com/index.php:140) in http://www.url.com/forums/includes/sessions.php on line 188

Warning: Cannot modify header information - headers already sent by (output started at http://www.url.com/index.php:140) in http://www.url.com/forums/includes/sessions.php on line 189

Note: i didn't edit any PHPBB Files, (sessions.php).

Here Are Lines 188 & 199 (sessions.php) :

[code:1:ee2159d088]
setcookie($cookiename . '_data', serialize($sessiondata), $current_time + 31536000, $cookiepath, $cookiedomain, $cookiesecure);
setcookie($cookiename . '_sid', $session_id, 0, $cookiepath, $cookiedomain, $cookiesecure);
[/code:1:ee2159d088]

Thanks in Advance .

Open http://www.url.com/forums/includes/sessions.php and make sure there are no blank lines at the end after ?>

Sometimes that is the problem.

[samer]

Nope .. No Blank Lines.

Make sure there is no information whatsoever being sent out to the page before the cookie is set.

[samer]

well, i'm kinda obliged to send info before sessions.php is open.

Well, that's what it's complaining about. You are trying to send header information after sending the headers, which you can't do. It might be trying to redirect the user, or send a cookie. Whichever it's doing, you'll get the error until you change it to send things in the right order.

, i didn't find a solution, but i have noticed something:
when i visit my forums before visiting my homepage, i don't get the error, because (i think) the cookie has been set.

so i have to found a way for the cookie to be set before accessing my homepage.. Help please.

I tried some php coding today. You cant do much if you have any HTML or PHP before the phpBB code - it complained to me about headers already sent. Had to stick the code at the very top of the page for it to work.

unreal, PM'ed ya.

Dumb question but are you sure you've CHMODDED it correctly?

[samer]
