Cannot modify header information - headers already sent by

Posted: Thu Jan 26, 2006 4:49 pm

Hi,

i have a strange problem. By now i know only from one person that he sees errors on my page. That no one else can see the problem confuses me a little bit.

The Problems are:

Code:

Warning: Cannot modify header information - headers already sent by (output started at /www/htdocs/xxxxx/xxxxx/Nukeroot/header.php:32) in /www/htdocs/xxxxx/xxxxxx/Nukeroot/includes/sessions.php on line 291

Warning: Cannot modify header information - headers already sent by (output started at /www/htdocs/xxxxxx/xxxxxx/Nukeroot/header.php:32) in /www/htdocs/xxxxxx/xxxxxx/Nukeroot/includes/page_header.php on line 501

Can anybody tell me, why only one person can see the errors and how i can get rid of them?

Thanks a lot,
spacy

Hi Spacy,

this problem was so often discussed and also the solution. I quess you know what I mean and in wich forums.
A link to your site would be better. So we can take a look with different browsers.

Thanks Susann for your answer. A little bit strange, two german people talk together in english *gg*
I've searched some forums such as this one here and also Warpspeed and havend found a solution and a answer why only one person can see the problem.
The link to my site is www.suche-hobby-partner.de

Quess we meet us now daily.My english is not up to date "gg" but anyway I found with the http viewer and different users strings no problems.Headers is 200 that means it´s ok.
Yes, I meant Warpspeed and the solution posted by Coldcut but why only one person got this error message was not answered.
Do you use the solution from Ravens Nuke FAQ for your htaccess ?

I forgot to post that the problems are only in the Forums, Private Message and the Memberlist-modules. You have seen only the index.php at my side.

I´ve got for your forums also Header 200 and can´t see this problem in your forums.
Btw: The index page and forums isn´t valid html.

thanks for looking it up. I already wrote to my hoster that he should change the output_buffering to on. I hope that then does no one have a problem.

By the way susann, can you tell me how you check if the page is valid html ore not?

hi spacy,you dont need your host for that,just put.......

php_flag output_buffering on

in your htaccess file.

Thanks hitwalker.
I realized this after sending the email to my hoster. When i wanted to change this it has already been done by the support (at 1 am within 5 minutes *gg*)

The changing of output_buffering doesnt solve the problem. The one user still sees all the errors. Does anyone have another hint for me?
BTW, I use RN76...

what browser is he using?

Posted: Sat Jan 28, 2006 5:51 am

Firefox 1.5. The only different ist that he is using a modem.

i figured that,this error only shows in firefox,i had the same...
if you search with google...cannot modify header....etc...you get a few million results.
ask that member to clear everything on his computer.....cookies,internet history..
keep in mind that if this is just a problem at 1 members computer then it has to be solved there,or use IE.
normaly the output buffering solves it...

Hello !

I have the same problem but whenever i put "php_flag output_buffering on"
into my .htaccess file the page becomes unaccessible and i get a server error..
i need to replace the htaccess file with the new one...

so how should i do it so that the site doesn't crash ?

forget it, i found the answer in the FAQ Embarassed

Where are supposed to be the lines, which should be deleted ?

I got that error some time ago and I resolved removing a newline, that don't know why was there, after the ?> at the end of a theme file (I don't remember which one but I think was theme.php)
