There have been SOOOOOOOOOO mnay posts about this. Hopefully this will fix it for you.

output_buffering MUST be set to on or 1
It has to be set either in the php.ini file or in .htaccess
It is NOT settable through the script using ini_set

Here would be the php.ini file

Code:

output_buffering = on

Here would be the .htaccess file

Code:

php_flag output_buffering 1

I've searched the forums and found only 1 other post that contains the same error that I am getting (the poster was told by you to do a search for 'error_reporting' to find a solution for the error). Here is the error again:

Notice: ob_end_clean() [ref.outcontrol]: failed to delete buffer default output handler. in /usr/home/gr8t/userfiles/public_html/mainfile.php on line 18

I've checked to ensure that ouput_buffering was enabled and it shows a value of 4096 in the default server settings:

http://www.gr8tservice.org/phpinfo.php

I assume that means it is enabled. Any ideas?

Thanks for you help!

Yes and no. Try setting it to On. I have documented cases where the two do not behave the same Smile

. let us know.

Well, after a bit of reading (and hair pulling) I think I've put my finger on the problem.

My Working Environment
FreeBSD 4.8-STABLE - PHP Version 4.3.1 - PHP-Nuke 6.5 - MySQL 3.23.56

Most of the errors that I was encountering were displayed only because my webhost provider has error_reporting set to the highest level (2047 or E_ALL). The majority of webmasters will not encounter this since the default error_reporting level will not force the messages to be displayed. By changing my error_reporting level I was able to suppress the majority of the errors.

The Errors

Notice: Undefined variable: HTTP_USER_AGENT in /usr/home/gr8t/userfiles/public_html/mainfile.php on line 16

This is an attempt to use an environment variable that has not implicitly been declared in the GLOBAL scope.
Changed

Code:

$HTTP_USER_AGENT

to

Code:

$_SERVER['http_user_agent']

Notice: import_request_variables() [function.import-request-variables]: No prefix specified - possible security hazard in /usr/home/gr8t/userfiles/public_html/mainfile.php on line 39

This looks like a fix from the register_globals change in PHP 4.2.0. Normally this wouldn't be seen so not a big deal. But it does raise some security questions...

Notice: Undefined variable: forum_admin in /usr/home/gr8t/userfiles/public_html/mainfile.php on line 69

An IF statement referencing an undeclared variable.
Changed

Code:

if($forum_admin) {

to

Code:

if(isset($forum_admin) && $forum_admin ==1) {

Notice: Use of undefined constant inside_mod - assumed 'inside_mod' in /usr/home/gr8t/userfiles/public_html/mainfile.php on line 72

Missing $ before the variable reference.

Notice: Undefined variable: inside_mod in /usr/home/gr8t/userfiles/public_html/db/db.php on line 44

An IF statement referencing an undeclared variable.
Changed

Code:

if($inside_mod) {

to

Code:

if(isset($inside_mod) && $inside_mod ==1) {

Fatal error: Call to undefined function: message_die() in /usr/home/gr8t/userfiles/public_html/db/db.php on line 88

This ones my favorite.......I mispelled my database password in config.php. When a database connection could not be established, db.php tried to display an error message. Unfortunately, functions.php was not included/required and the function was not defined.

Hope this helps somebody who encounters the same problems.

I never even noticed the word Notice Embarassed

I could have fixed that immediately. Sorry! We even tell you that in our Welcome Announcement and have answered it many times here. Well, look at all you learned Smile

. Thanks for sharing!
