on your latter point, I am just a moderator here, and not a bbpress author.

The authors tend to release updates every few years, rather than more frequently.

My personal view is that you should consider bbpress to be a ‘mature’ product, ie any releases will be to fix issues rather than add functionality.

bbpress is written really well, and has loads of hooks. In essence it is a WordPress product, written by the founder of WordPress, and taken into a plugin by sponsorship from WordPress.
There are no show stopper bugs in it, it may throw a few notices (and these are very few at the moment), but WordPress recommends that you should not show error messages in live sites.

I currently have my test site running WordPress 6.9 and php 8.2 with no issues.

The only major issue with bbpress at the moment is that it does not work well with FSE themes.

However my bbp style pack plugin has fixes for this

bbp style pack

as well as block versions of the widgets and a ton of styling and functionality add-ons.

All plugins are subject to the authors commitment, and bbpress is no different.

@mike80222 thanks for sharing… In ur case its a clean install and we see every error is in the bbpress folder specifically:
…/wp-content/plugins/bbpress/includes/common/functions.php on line 1581

@robin-w I’ll try a bit of what you said for our environment and see if it curtails the issue.

also Robin; can you share a reply on this please? “I ran bbpress through Plugin Checker (WordPress official) and there are a lot of things that might be pinging this, not sure if the team are addressing performance, repo, general and the security issues raised in it”.

[Mike Witt]

Just my two cents worth. I don’t actually understand this issue, but this crops up on all my sites on AWS Lightsail. I’ve had some success defining those PHP variables in wp-config.php, but it doesn’t always work. Searching on things like “http_host undefined” yields some interesting information which might help. I’m pretty sure that this is not actually specific to bbpress.

[Robin W]

ok, thanks.

the line of code referred to is looking for a host url on logout from bbpress.

‘$redirect_to = bbp_get_url_scheme() . $_SERVER[‘HTTP_HOST’] . $_SERVER[‘REQUEST_URI’];’

$_SERVER is a php thing and the manual says ‘$_SERVER an array containing information such as headers, paths, and script locations. The entries in this array are created by the web server, therefore there is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here. However, most of these variables are accounted for in the » CGI/1.1 specification, and are likely to be defined.’

Are you maybe running on a local host?

[pineapplepalm]

Thank you for responding.

It’s happening constantly in our server domlogs. It’s a new site install. No active forum yet site isn’t launched yet. Seems to be happening simply from the site existing with bbpress on it.

I ran bbpress through Plugin Checker (WordPress official) and there are a lot of things that might be pinging this, not sure if the team are addressing performance, repo, general and the security issues raised in it?

Please can something be done about this error on a brand new site install:

Would appreciate some feedback please

[Robin W]

on the translations, these are part of buddypress not bbpress, so you would need to ask the question on their support forum

https://buddypress.org/support/

on the grey box, what exactly do you want to change?

[Robin W]

suspect this is an AI generated spam, but in case not,

bbpress latest version is 2.6.14 and was updated 4 months ago.

[mickeljn]

Hi all — today my Wordfence scan threw up a message saying the bbPress plugin “appears to be abandoned” (last updated Nov 29, 2021, tested to WP 6.3.2) and labelled it under a “Vulnerability Scan” result. I’m surprised because I’ve been running bbPress on a few sites and didn’t expect that kind of warning.

Has anyone else seen this exact Wordfence message recently? I’m trying to understand whether this is a false positive from the scanner or if there really is an issue with maintainer activity/compatibility. A few quick notes about my setup that might matter:

WP version: 6.3.2

bbPress version: (latest I have installed)

Hosting: shared (no custom hardening beyond basic security plugin)

I’m mainly looking for other users’ experiences — did Wordfence give you the same warning? Did you find official confirmation about bbPress maintenance status, or any advisories/CVEs? Also curious if anyone can point to a reliable source that tracks plugin maintenance/activity (GitHub, WP plugin repo changelog, etc.) so I can verify on my own.

[Robin W]

I’m pretty sure that the buddypress function hooks to the new_forum_handler in bbpress, so this should work

add_action( 'bbp_new_forum_post_extras', 'rew_add_pg', 10 , 1) ;

function rew_add_pg ($forum_id ) {
	 add_post_meta( $forum_id, '_private_group', 'group1', false );
}

Let me know of not.

[bbbt]

Hi,

We use bbpress, buddypress, and bbp-private-groups in a WordPress installation.
Thank you for the great plugins!

In the Buddypress Group Settings, the group administrator can also create a forum.
How can I add a specific group from bbp-private-groups to a group forum when creating the group forum?
I couldn’t find an option for this in the backend settings.
Is there a suitable hook? I don’t know the forum ID yet for “groups_group_after_save”.
I would add the group with add_post_meta( $forum_id, ‘_private_group’, ‘group1’, false );.

Thanks for any tips!

Bonjour,

Connaissez-vous un plugin similaire à “Post Comments as bbPress Topics” ?
Merci d’avance.
Bonne journée.

[oxyjane]

Good evening,
I can’t seem to find the solution, so I’m posting my question here.
In WordPress, I have a bbpress forum. Some old posts (from 2016) are visible to me (Key Master), but no longer to subscribers (private forum). So there seems to be a system that hides these posts after an expiry date (not the first post, but the replies). I can’t find anything in the general settings or in the bbpress plugin. I also have bbP private groups and bbPress Notify (No-Spam). Any idea what the problem might be?

[Robin W]

If you are using a block theme, then you will need to add theme support for bbpress.

so either

Install

bbp style pack

once activated go to

dashboard>settings>bbp style pack>theme support

This plugin has lots of styling and functionality additions to bbpress

and/or use

Enable bbPress for Block Themes

[miwonheo]

I recently discovered that WordPress.com’s Personal and Premium plans allow plugin installation, so I immediately paid and installed bbPress.

However, a similar forum plugin, WPFORO, works fine, but after installing bbPress, when I go to the actual forum page (myid.wpcomstaging.com/forums/forum/test/), it just displays a blank screen, with neither my blog’s theme nor the forums displayed.

Just in case, I tried disabling my browser’s ad blocker and changing my theme, but the results were the same!

I asked a question on the WordPress.com forums and was directed here. Has anyone else encountered a similar issue? What solutions have you found?

[donal13]

Hi,
Google are saying that it is not listing my forum posts because

“Either ‘text’, ‘image’ or ‘video’ should be specified”
Items with this issue are invalid. Invalid items are not eligible for Google Search’s rich results”

How can I sort this.
Google has the topics listed, so its seeing them. I send a sitemap to Google.
It is important that these topics are listed by Google.
I would appreciate any help.

I am using BBpress Version 2.6.14

Thanks

[Robin W]

there are lots of causes that will show this error, many plugins load the bbpress text domain.

If you are running buddypress, then you can stop a bbpress file from causing the error by the fixes above, or by using :

bbp style pack

once activated go to

dashboard>settings>bbp style pack>bbPress bug fixes and go to

Fix bbPress domain triggered early if Buddypress also active

Hi @dragoeco,

I’ve been using the patch you suggested above about 5 months ago, and it’s been working fine for me. As far as I can tell, this is something that should be fixed in bbPress. But as I mentioned I’m a bit out of my depth. If somebody knows different, they will hopefully correct me.

[Vinay PN]

Here are some ways to add or customize the title and meta description for the bbPress forum index:

1. Use an SEO Plugin That Supports Custom Post Types and Archives
bbPress forums often rely on custom post types and archive templates.

Ensure Yoast SEO is configured to handle bbPress custom post types and their archives.

In Yoast SEO > Search Appearance > Content Types and Archives, check if bbPress forums and topics are enabled and configured properly.

For the main forum index (bbPress’ main forum page), this is often considered an archive page. Yoast allows customization of archive titles and meta descriptions via the Archives tab.

2. Add Custom Code via Functions.php or a Custom Plugin
You can programmatically set the title and meta description on the bbPress forum index with code snippets. For example:

php
function custom_bbpress_forum_index_seo() {
if ( function_exists( ‘is_bbpress’ ) && is_bbpress() && !is_singular() ) {
// Set custom title
add_filter( ‘pre_get_document_title’, function() {
return ‘Your Custom Forum Title – Your Site Name’;
});

// Set custom meta description
add_action( ‘wp_head’, function() {
echo ‘<meta name=”description” content=”Your custom meta description for the forums index page goes here.” />’ . “\n”;
});
}
}
add_action( ‘wp’, ‘custom_bbpress_forum_index_seo’ );
This snippet checks if it’s a bbPress page but not a single topic or forum (index page), then overrides the title and adds a meta description.

3. Use a Dedicated SEO or Meta Tag Plugin
Alternatively, plugins like All in One SEO, Rank Math, or WP Meta SEO may provide greater flexibility to add meta tags for archive/custom pages.

4. Use a Page as a Forum Landing Page Instead of bbPress Default
Instead of using the default bbPress forum index, you can:

Create a regular WordPress page.

Use that page as your main forum landing page.

Insert bbPress shortcodes or specific forum content there.

This way, you can edit the page’s SEO title and meta description directly with Yoast.

I just saw your message @mike80222

I said “bbpress is not causing it.” because Robin said that in this message : https://bbpress.org/forums/topic/php-notice-on-version-2-6-11/#post-243051

I have given up trying to find the source of the error tbh. I just deactivated debugging mode. It’s the best solution (for now), but it’s just annoying when you have to debug a problem and you have dozens of similar lines.

[thomasjarvisdesign]

Sorted – The front end issue is a CSS error made by us.

The back end issue is a problem with DiviAI and not caused by BBPress itself.

The temp fix is to disable DiviAI from the Divi>Role Editor for all users including the admin.

I have raised this issue with Divi asking for a fix in Divi5 when it gets released.

ok, so bbpress will show before the site is published

does bbpress show as active in

do you have
