Error with new Nuke Sentinel 2.5.00

linksysinfo · New Member Joined: Aug 06, 2005 Posts: 9

Just installed the new 2.5.00 version. upgraded from 2.4.2pl9 using upgrade script.

the first time i open a browser and goto my website i get

Warning: ob_start(): output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in /home/linksys/public_html/mainfile.php on line 120
above the header

anyone have a fix? for that?

I'm running Nuke Platinum 7.6.x (with all of Technocrats fixes)

linksysinfo · New Member Joined: Aug 06, 2005 Posts: 9

line 120 is:

ob_start('ob_gzhandler');

I have changed this to:

ob_start();

will this incur any problems with the site?

You might want to check with Technocrat, but is it possible that you have gzip compression enabled in your Forum configuration settings? Do you see this only when you are in the Forums, Members LIst or Private Messages? If it is everywhere, then I would definitely check with Technocrat as to the proper edit to make.

He checked with me already and I am unsure why PNP has this problem. I have the same issue with my (now dead) PNP site too when I did the upgrade. Must be something with the way PNP starts the gzip session.

You can try this fix and see if it works especially if you are running PHP 4.3.x:

Since its the mainfile that has the gzip part of this code, this change would probably not help.

same error here,i use a Platinum site and it comes up with this error above header,and its not allways,also,it start since i upgraded Sentinel to 2.5.

And all of you that have this issue have 'enable gzip' turned OFF in the forum config?

DarK_Gamers · Posted: Wed Jul 12, 2006 3:37 pm

Warning: ob_start(): output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in mainfile.php on line 99

this seems to have fixed this issue, no one yet has complained. though am moving to vB soon.

To skip displaying this warning, you should change the error_reporting`s value to E_NONE & ~E_NOTICE in your php.ini file.

Code:

Error_Reporting(E_NONE & ~E_NOTICE);

I have this error in my error log:

Code:

[error] PHP Warning: ob_start(): output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in /home/mydomain/public_html/mainfile.php on line 100

for about 100 iterations. I'm going to try linksysinfo's fix. I have gzip off, too. I recently upgraded tto NS 2.5.00.

It worked for me, without any problems, however i have now, sorry to say, moved over to the dark side.... to vBulletin

One more suggested fix for this. Place the following in your root .htaccess file:

php_flag session.use_trans_sid off

This problem has been bugging me for some time now....hehe

Would you please explain the effect and possible risk of:
php_flag session.use_trans_sid off

I noticed that my NSNST_Flood session ids from urls and title tags are gone.

Interesting

Actually I was doing some SEO, and noticed this helped my site....

I don't know of any bad effect unless the browser visiting your page doesn't accept cookies. The plus is, for some sites, it increases your SEO.

Provided flood blocker works by 'counting' hits from a specific IP or referer or useragent (or a combination) then I do not see any reason why this would affect its effectiveness.

I see from the article they recommend using

Code:

ini_set('session.use_trans_sid', false);

which might be another way to remove session ID's particularly for the forums for anonymous users.

Susann · Posted: Mon Jul 24, 2006 1:26 pm

Normally I´m more skeptically but I use it until I find strange things in my logfiles or the flood blocker. I don´t have real traffic currently so I can´t check the behavior of different bots.But the good thing is that fixed automatically my validation problem.

That is an interesting implementation. Was also considering it for removing the SSID's in phpBB for the "GoogleTap" crowd. Didn't get far enough into trying it. I may have to now. But wasn't really sure how phpBB used sessions. I was needing to analyze that first.

As Dauthus has commented, though, it might even kill session handling for browsers without cookies enabled. So, with everything, is the trade-off worth it? In this day-and-age, I would say "yes". Almost EVERY site on the web that we use on a daily basis (I am meaning things like our banks, purchasing, etc.) use cookies.

Hi!

I had the same problem: "Warning: ob_start(): output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in /home/public_html/mainfile.php on line 98" above the header...
Using the Dauthus tips (in quote)...

... I had the following changes in mainfile...

Quote:

// After doing those superglobals we can now use one
// and check if this file isnt being accessed directly
if (stristr(htmlentities($_SERVER['PHP_SELF']), "mainfile.php")) {
header("Location: index.php");
exit();
}

if ($phpver >= '4.0.4pl1') {
ob_end_clean();
ob_start('ob_gzhandler');
// }

... and the site is working perfectly.

Just forgive my bad english, ok?

Thanks!!!

mpaschoal, Thanks for verifying this for me. It worked for me too, but everyone seemed to think I was on the wrong track, so I just figured I would leave it alone and dig around for another method.

I came across the last one by accident while trying to up the SEO, and it seemed to work too, so I threw it in the mix.
