index.php I get error in header

Nuke Soldier Joined: Jul 01, 2003 Posts: 18

I have instaled Nuke 6.5 on my computer (server and everything) and upload it (plain upload not a web instalation) on server.

But there is a problem...when I open a index.php I get error in header what says:

Warning: Cannot modify header information - headers already sent by (output started at /home/php-nuke/public_html/mainfile.php:2) in /home/php-nuke/public_html/mainfile.php on line 166

What is a problem?

Sometimes I get error in other lines...157, 177 and cetera.

Warning: Cannot modify header information - headers already sent by (output started at /home/php-nuke/public_html/mainfile.php:2) in /home/php-nuke/public_html/modules/Your_Account/index.php on line 766

If you have access to php.ini, set
output_buffering = On
and then restart your server
otherwise add this line to a .htaccess file
PHP_FLAG output_buffering On
and place it in your web nuke root.

Wow... I edited the .htaccess file since I haven't got access to the php.ini file and it just gave me a nice 500 Internal Server error!

My error logs reported the following:
[Wed Oct 1 13:40:11 2003] [alert] [client 62.253.64.9] /www/f/firewall/htdocs/.htaccess: Invalid command 'PHP_FLAG', perhaps mis-spelled or defined by a module not included in the server configuration

Any ideas ?

After checking the php version my hosting company is running .. i found its 4.3.1, perhaps it dosen't understand this flag and needs to change slightly ?

Here is the relevant php.ini section from analyzer.php:

[output_buffering] => Array
(
[global_value] => 1
[local_value] => 1
[access] => 6
)

I should have told you to check to see if OB was already on. Sorry Embarassed

The server error means they do not allow you to use .htaccess. Just delete it.

My hosting company does allow me to use the .htaccess file Raven.
I've been using it for over a year to specify the error file when someone hits an invalid page.

Any other ideas ?

But they are restricting your use of it. error file overrides are Apache related. They are not allowing overrides to PHP variables through Apache. In any event, OB is already on so that is not the resolution to your problem.

If its any help, I have noticed that the errors will occur only when private messages or posting to threads that contain old users, and by this I mean users that existed in the forums before I imported them to php-nuke's phpbb.

I was running my server, and suddenly the error just started to happen. Naturally I did not refer to this site, and spent quite a few hours probing in the dark Shocked

Then I found this thread, and now the problem is fixed Razz

by putting the line in .htaccess. I don't know why the problem suddenly started to happen, but I am not going to worry about it (unless it happens again).

Thank you, Raven!

Ok, I've tried the mainfile.php fix, I did the .htaccess file, I tried the ini_set script, output_buffering is on on the server - I still get the "cannot modify header information - headers already sent" error on my Forum.
The problem occurs in IE, Mozilla and Opera.

Does anyone have any idea what this can be?
Please - I don't have much hair left Wink

I have the exact same problem with forums and have tired the above fixes to no avail Mad

Does anyone know another fix to try?

Environment - Nuke 7.0, Apache 2, Solaris 8

Terbeaux, My error was generated by "sessions.php". So I commented out the lines that caused the problems as suggested in this post:
http://nukecops.com/postt739.html.

Now it seems to be working. Laughing

I am however not sure what implications there might be by not updating your header info. Wink

Try it.
