“Cannot modify header information – headers already sent”

is one of those errors that will fool you by distraction because it’s an indication of another error, that happened before it, it’s not the actual primary error.

“headers already sent” means one of the following (among other possibilities)

1. You have whitespace at the start of end of a plugin (or template) BEFORE or AFTER the <?php ?> (usually after the end. Whitespace means new lines or spaces.

OR

2. Another plugin or configuration error has occured and sends a text message, which causes the headers to be sent. To find out what the real problem is, you typically can do a “VIEW SOURCE” on the page (from your browser menus) and you’ll see in plain text at the top of the page the real error before the “headers sent” error.

Hello,

I wrote this for my own use, in case it could be of some use for someone, here it is :

http://pastebin.com/f35e5dcbe

This allow to put some html code in header (or example metatags) and footer (for example counter code)

There is no admin part for two reasons :

1) I’m learnig how it works

2) I’m not sure it would be a great idea to have a DB request for a code that never change

So for instance you’ll have to edit manually the plugin file

Why use a plug in instead of a direct ad in the template ? because for alpha release the default template (my own is based on kakumei) sometimes change, so keeping the personal code updated each time can be tedious.

By the way, once you are done with this, we’ll install eAccelerator and that will give your PHP a nice boost too.

Let me know how the MySQL cache mod goes.

If you don’t want to wait and feel comfortable trying it right away, try downloading and using this script to auto-install eAccelerator on Cpanel:

wget http://tutorials.medialayer.com/cPanel/eaccelerator.sh

chmod 700 eaccelerator.sh

./eaccelerator.sh

Once it is done, you might have to restart apache

service httpd restart

and you should definitely notice another speed boost.

[_ck_]

Untested. auto-closes a topic on-the-fly when someone visits it and it’s last post is 90 days old (adjustable)

add_action('bb_head','auto_close_topic');

function auto_close_topic() {

global $topic;

if (is_topic() && $topic->topic_open===1) {

$old=time()-3600*24*90; // 90 days default

if (strtotime($topic->topic_time)<$old) {

bb_close_topic($topic->topic_id);

$topic->topic_open=0;  // just in case the cache doesn't clear

}

}

}

[_ck_]

Okay, carefully edit your /etc/my.cnf (ask if you don’t know how to edit) and REPLACE what’s in there with this:

[mysqld]

max_connections = 400

key_buffer = 16M

myisam_sort_buffer_size = 32M

join_buffer_size = 1M

read_buffer_size = 1M

sort_buffer_size = 2M

table_cache = 1024

thread_cache_size = 286

interactive_timeout = 25

wait_timeout = 1000

connect_timeout = 10

max_allowed_packet = 16M

max_connect_errors = 10

query_cache_limit = 1M

query_cache_size = 16M

query_cache_type = 1

tmp_table_size = 16M

skip-innodb

[mysqld_safe]

open_files_limit = 8192

[mysqldump]

quick

max_allowed_packet = 16M

[myisamchk]

key_buffer = 32M

sort_buffer = 32M

read_buffer = 16M

write_buffer = 16M

[mysqlhotcopy]

interactive-timeout

After you edit it you’ll need to restart the mysql engine by typing this in the ssh:

service mysql restart

(optionally there’s also a mysql restart in cpanel)

Then do a couple of refreshes on your bbPress pages and it should seem a bit zippier.

[lstelie]

_ck_

In latest bb-config.php there is no /* Stop editing */

Do I put $bb->load_options = true; at the end of the file ?

[meitershaker]

same problem here

[meitershaker]

$hidden_forums=array(10); // hide these forums, list by comma seperated number

$hidden_forums=array(‘keymaster’,’administrator’,’moderator’); // these roles can always see ALL forums regardless

$hidden_forums[500]=array(‘administrator’,’moderator’); // exact formal role name, *not* ability

$hidden_forums[501]=array(‘administrator’,’moderator’); // exact formal role name, *not* ability

$hidden_forums=array(1); // these users can always see ALL forums regardless

$hidden_forums[500]=array(5432,7654); // list of users by number

$hidden_forums[501]=array(5432,7654); // list of users by number

$hidden_forums=””; // text, html, css or image to indicate hidden forums/topics, make it =””; if you don’t want any label at all

[_ck_]

Well it works for me.

Show me your configuration inside hidden-forums.php and how many forums do you have?

Are those queries happening on the front-page, forum-page or topic-page?

[cartmanffc]

Where exactly should I put this code in post-form.php?

<textarea name=”post_content” cols=”50″ rows=”8″ id=”post_content” tabindex=”3″>

<?php if (function_exists(‘bb_quote_post’)) bb_quote_post(); ?>

</textarea>

[cartmanffc]

I thought it might be helpful; I tried the following popular plugins with the latest release of bbPress and they seem to work perfectly:

– bb-smilies

– bbcode-buttons

– mini-track

– my-views

– post-count-plus (with some minor changes)

– support-forum

– bb-reputation (to some extent)

– bb-signatures

– bb-topic-views

– bbcode-lite

– hidden-forums

– report-post

– unread-posts

what is missing most is the working plugin for quotes…

[_ck_]

Show me your mysql configuration by doing this in your shell (ssh)

cat /etc/my.cnf

and copy what it returns to a post here or into pastebin.com

I suspect we can improve it. MySQL cache is very important to bbPress performance.

[_ck_]

You (and everyone) needs to make sure this is in your bb-config.php

$bb->load_options = true;

make sure you put it BEFORE /* Stop editing */

[_ck_]

Running bbPress on a server with 128mb of ram would be very difficult unless it’s a very light setup with low use.

256mb should be doable if that is real, permanent memory and not burst memory. It’s also important if you don’t have alot of overhead like cpanel running.

#1 problem on most small VPS is you either don’t have the mysql cache turned on or it’s too small of a cache

#2 problem is you almost certainly don’t have a PHP opcode cache like eAccelerator installed

#3 problem on almost all VPS is bad neighbors.

On a shared host, you can easily tell when you have bad neighbors who are overloading the server (node). On a VPS they are hidden. If you have an inexperienced host, they may have a hard time tracking down the offender, or may not even care. If they tell you that your neighbors can’t affect you, that’s an outright lie or plain ignorance.

If you are running bbPress 1.0 alpha it has several problems generating far too many mysql queries and that could be causing you some headaches. If you are using bbPress 0.9, definitely stick with that, but you need to fine tune your settings.

WordPress has some nice caching plugins like wp-super-cache. No such creature exists yet for bbPress, so all pages must be rendered each time by the engine, making it use more overhead than WordPress.

[darnit]

I found the answer myself, 26 mins. later, LOL: you simply need to go to Manage -> Forums -> click on a forum and set its parent forum.

That way you’ll have multiple subforums on any forum on your bbPress installation.

Heh. Next time, I’ll get acquainted with the features of bbPress BEFORE asking for help

[darnit]

Hello bbpress world!

I would like to congratulate you all for developing such a steadfast, easy-to-use forum software known as bbPress. I love(s) it

Secondly — yeap, it’s an issue — I would like to know if it is possible to have a forum-forum-topic structure instead of the current forum-topic one.

For example, we currently have:

Webmasters Forum – [all the topics go here]

while we would want to have:

Webmasters Forum – Italian Webmasters Forum / American Webmasters Forum – [all the topics from the Italian / American go here]

Would such a structure be possible?

Thank you for your time and for your replies.

Hi,

i have a serious bug: when i’m not login, i have 610 mysql query, and there is a one query repeat:

# 416 : 0.0004 seconds

SELECT meta_key, meta_value FROM bb_meta WHERE object_type = 'bb_topic' AND object_id = 37 /* bb_append_meta */

# 417 : 0.0005 seconds

SELECT * FROM bb_topics WHERE topic_id = 37 AND topic_status = 0 AND forum_id NOT IN (10)

# 418 : 0.0004 seconds

SELECT meta_key, meta_value FROM bb_meta WHERE object_type = ‘bb_topic’ AND object_id = 37 /* bb_append_meta */

# 419 : 0.0005 seconds

SELECT * FROM bb_topics WHERE topic_id = 37 AND topic_status = 0 AND forum_id NOT IN (10)

why?

when i’m login at admin, i have no this!!

i use mini track, bb_topic_wiews, bb_benchmark and topic_icons plugin

please help me

[bryan868]

So what was the outcome from the Summer of Code? Did we get a phpBB 3.0 converter?

[meitershaker]

hi, how to give the possibility of all users to see the report in the source code, please?

bye

[Sonika]

Detective, thanks a lot!!!

It solved my problem ( wp 2.5.1, bbpress 0.9.0.2)

Bo Fiddlesticks, you should save code in set-default-role.php file, put it in bb-plugins and activate

<?php

/*

Plugin Name: bbpress wpmu default role

Plugin URI: https://bbpress.org/forums/topic/yet-another-integration-bug-no-role-set-on-registration?replies=5

Description: Sets a default WPMU role for all new bbpress users.

Author: Detective

Author URI: http://www.ryuuko.cl/

*/



function wpbb_add_user_role_rk($user_id) {

$user = new WP_User($user_id);

$user->set_role(get_option('default_role'));

}

add_action( 'bb_new_user', 'wpbb_add_user_role_rk');

?>

[brad_langdon]

I think for the target audience I have that is not ideal.

It’s for a jet boating forum so the majority of my users are very outdoorsy and not that computer savvy.

They are used to uploading pics on other forums and having them show up straight away. It makes sense. Why would you go to all of that trouble when other forums do it for you automatically.

Is there a way to modify the plugin code?

When you click insert it must do something so cant we just take that code and put it in the appropriate place ao that it does it straight after uploading?

Sorry if that is a stupid question, I am far from an expert.

[Jens Wedin]

Here is a function list for the v1.0 alpha one. As the developers do not add any documentation I found this on the net. You can you this by your own if you have an older or newer version of bbPress by doing this command in the terminal (linux or mac):

grep -oe ^function.*) bb-includes/template-functions.php | sort > functions.txt

This idea is Tims (http://timjoh.com), I used updated his idea.

@Thion – I think 2018-2019

bbpress needs all (all current and all “release critical” bugs at least) bug fixes … and 3-4 relatively small enhancements.

I think regular (every 4-5 weeks) alfa-s will be useful.

[_ck_]

The login form is so low because you specified position bottom -200px and that means for it’s parent element.

.login {

position: absolute;

bottom: -200px;

If you wanted it 200px from the bottom of the header, that means either the header is not being closed properly or the header needs a position:relative;

#header {position:relative;}

or you could just change it to position from the top:

.login {

position: absolute;

top: 20px;

I am also concerned that it takes nearly half a minute for a page to completely load on your site.

[chrishajer]

The wp-config-sample.php for WordPress 2.5.1 most DEFINITELY has that constant (line 13). Maybe you upgraded and used an old wp-config.php. You would never see the new constants unless you updated a wp-config-sample.php with your old database details.

// Change SECRET_KEY to a unique phrase.  You won't have to remember it later,

// so make it long and complicated.  You can visit https://api.wordpress.org/secret-key/1.0/

// to get a secret key generated for you, or just make something up.

define('SECRET_KEY', 'put your unique phrase here'); // Change this to a unique phrase.
