'header already sent' in forum

Nuke Cadet Joined: Jun 04, 2003 Posts: 1

I'm recently installed the PhpNuke 6.5 on linux with apache2.0.45 and php4.3.2RC. 
When I first browse the Forum section, it showed the warning: 

Warning: Cannot modify header information - headers already sent by (output started at /data/projectweb/header.php:32) in /data/projectweb/includes/sessions.php on line 222 

Warning: Cannot modify header information - headers already sent by (output started at /data/projectweb/header.php:32) in /data/projectweb/includes/sessions.php on line 223

Anyway, I finally find a post here and solve it by modifying the mainfile.php as mentioned by chatserv. 

However after I upgraded the apache to 2.0.46 and php to 4.3.2 today, this problem occurs again and now I don't know how to solve it. 

Does anyone of you get an idea on solving it?

Thank you very much.

Two options:

Quote:

Near the start of mainfile.php find:

$phpver = phpversion();
if ($phpver >= '4.0.4pl1' && strstr($HTTP_USER_AGENT,'compatible')) {
if (extension_loaded('zlib')) {
ob_end_clean();
ob_start('ob_gzhandler');
}
} else if ($phpver > '4.0') {

change to:

$phpver = phpversion();
if ($phpver >= '4.0.4pl1')
{
ob_start('ob_gzhandler');
}else if ($phpver > '4.0') {

and:

add the following line to a .htaccess file placed in your root Nuke dir.

Code:

PHP_FLAG output_buffering on

or if you have access to your php.ini, set:

Code:

output_buffering=on;

Thank you very much "chatserv"..I have solved the problem......

With this

Near the start of mainfile.php find:

$phpver = phpversion();
if ($phpver >= '4.0.4pl1' && strstr($HTTP_USER_AGENT,'compatible')) {
if (extension_loaded('zlib')) {
ob_end_clean();
ob_start('ob_gzhandler');
}
} else if ($phpver > '4.0') {

change to:

$phpver = phpversion();
if ($phpver >= '4.0.4pl1')
{
ob_start('ob_gzhandler');
}else if ($phpver > '4.0') {

ok i hope this gets answered her..I didn't look to see how old this post was..Anyhow i get the following error in my forums area of my site..

Warning: ob_start(): output handler 'ob_gzhandler' cannot be used twice in /data/members/free/tripod/uk/e/c/l/eclipsegsxr/htdocs/includes/page_header.php on line 98

my question is would the above post fix my problem also or do i need to look at something else?

also when i try to create New Area in the Forums Nothing Shows up..Could the above mentioned warning be causing my forums to not works?

Any help is appreciated..

Hello,

when I add PHP_FLAG output_buffering on to my .htaccess file I get:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

phpinfo on gremiumkr.cuni.cz/info.php

.htaccess look like:

Code:

DefaultCharset iso-8859-2
PHP_FLAG output_buffering On

How to solve this?

I also have the .htaccess file uploaded with what has to be there and i changed my mainfile.php:

http://clantx.t35.com:8000/.htaccess
http://clantx.t35.com:8000/mainfile.php

Try removing DefaultCharset iso-8859-2 from the htaccess file, also check if your server allows htaccess files, some don't.

My provider solved this by setting output_buffering=1 in php.ini.

Where did you get started learning to program PHP? What books?

Ah come on let's be fair, there's a nice Virtual Pinball game one can also play.

To be honest i've read no books, at least none relating to php, i learned by reading through forums and "breaking stuff to see how it works"

I've played that game too, but it crashed the OS & my activation expired so m1cr0$of7 wants to prosecute me because of a DMCA violation since I don't want to pay them to renew it!! Rolling Eyes
