ok, I am not a bbpress author, just someone who tries to help out.

So it’s Sunday morning here in the UK, and I have guests coming for lunch, so I will try and pick this up later.

But let’s just eliminate some stuff.

1.

dashboard>settings>permalinks and just click save – this resets the permalinks and may help

2.

it could be a theme or plugin issue

Themes

As a test switch to a default theme such as twentytwenty, and see if this fixes.

Plugins

If that doesn’t work, also deactivate all plugins apart from bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

If you cannot do this to your site (say because it is live) then use the ‘troubleshooting’ features of this plugin to let you test without affecting other users

Health Check & Troubleshooting

Then come back

Hi. I have encountered this problem: after installing bbpress and converting Mingle forum (this operation was not without problems), in some topics some permalinks are generated with wrong pages.

For example, following this link…:
mydomain/bbforums/topic/stream-records/page/8#post-121032
(I deleted the real domain since my thread was marked as spam, but I can provide it below if needed.)

… we get to page 8 and go down to post 121032 – the second one on that page. But if we go up to the first post on this page, we can see that the link to it is formed as “…/page/7#post-120964″ – as if the post was located on the previous page. Also, if you go down to the bottom of this page, you will see that the last posts are formed as “…/page/9#post-121104″. – that is leading to the next page.

Of course, I experimented with the settings of the paginator, changed the number of displayed posts on the page. In fact, it didn’t change anything, only the posts with the same error were changed. At the same time, if you do not change the settings of the paginator, a few posts with an incorrect link managed to “cure” by splitting the topic starting from this post, and then connecting the new topic with the previous one. But the above post didn’t work, so we can’t say that this is the solution.

I suspect that the cause of the problem may be an incorrectly performed forum import operation, but this operation was not easy (all posts were initially converted as replays and I had to manually correct their status in the database, also some posts were duplicated and were in the wrong id-order) and I would like to understand what exactly can cause this problem and how to fix it.

Of course I’ve already tried bbpress’ built-in error correction options, but they didn’t have any effect.

It’s strange that the paginator seems to be working correctly – it gives the right number of posts per page, and links to these pages also work correctly, but the permalinks with anchors are not working correctly.

Maybe someone has encountered a similar problem and can advise in what direction to look for its solution?

Tech info:
WordPress Version: 6.8.1
Current WordPress Theme: Twenty Fourteen/twentyfourteen-garage version 1.2
PHP Version: 7.4.33
MySQL Version: 10.6.22-MariaDB-0ubuntu0.22.04.1
bbPress (2.6.14)
bbP private groups (3.9.7)
bbp style pack (6.3.9)

the last two plugins do not affect the problem, when you turn them off it remains

[tonernews]

Since bbPress is owned by WordPress and since our site was built with WordPress, we are trying to figure out what happened to the tens of thousands of VIEWS that use to show up inside your bbPress app, now they have disappeared.

any help would be appreciated.
thanks

Doh! Lawdy me, how stupid can I be? Deepest apologies.

I do want to retain the private groups, so please forget that side of things.

It is “Front End PM” that I want to remove, and disabling that has re-introduced the fatal error on the forum pages.

The debugging reports:

Fatal error: Uncaught Error: Call to undefined function fep_current_user_can() in /home/signalbo/public_html/wp-content/plugins/code-snippets/php/snippet-ops.php(584) : eval()’d code:5 Stack trace: #0 /home/signalbo/public_html/wp-includes/class-wp-hook.php(324): {closure}(”) #1 /home/signalbo/public_html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(NULL, Array) #2 /home/signalbo/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #3 /home/signalbo/public_html/wp-content/plugins/bbpress/templates/default/bbpress/loop-single-reply.php(56): do_action(‘bbp_theme_after…’) #4 /home/signalbo/public_html/wp-includes/template.php(812): require(‘/home/signalbo/…’) #5 /home/signalbo/public_html/wp-content/plugins/bbpress/includes/core/template-functions.php(103): load_template(‘/home/signalbo/…’, false) #6 /home/signalbo/public_html/wp-content/plugins/bbpress/includes/core/template-functions.php(41): bbp_locate_template(Array, true, false) #7 /home/signalbo/public_html/wp-content/plugins/bbpress/ in /home/signalbo/public_html/wp-content/plugins/code-snippets/php/snippet-ops.php(584) : eval()’d code on line 5

so I understand from that the error lies with the code-snippets plugin although as yet I’m not quite sure where to start on that. I’ll give it some thought but if you have any suggestions they wuld be appreciated.

[finallyfoundausernamenotusedbefore]

My forum at https://signalbox.org/the-blower/ is broken after the update to v2.6.14 – I cannot tell if the cause is BBPress itself or one of the various plugins I use.

The error message can be seen by viewing any post.

Any help appreciated.

[Robin W]

1. yes, this is the intended behavior
2. yes, that behavior is set by a function which is called by an action, so we can remove it, and do something else.

so untested, but this should work

remove_action( 'bbp_template_redirect', 'bbp_forum_enforce_blocked', 1  );

add_action( 'bbp_template_redirect', 'rew_forum_enforce_blocked', 1  );

function rew_forum_enforce_blocked() {

	// Bail if not logged in or keymaster
	if ( ! is_user_logged_in() || bbp_is_user_keymaster() ) {
		return;
	}

	// Set 404 if in bbPress and user cannot spectate
	if ( is_bbpress() && ! current_user_can( 'spectate' ) ) {
		//DON'T DO THE SET 404 ie this is the code that the default bbp_forum_enforce_blocked does
		//bbp_set_404();
		// DO SOMETHING ELSE HERE!
	}
}

What the something else is, you will need to decide

Put this in your child theme’s function file –

ie wp-content/themes/%your-theme-name%/functions.php

where %your-theme-name% is the name of your theme

or use

3. I can’t say what the original authors intentions were, but I suspect yes

[jfbprivate]

Hi there,

I’m running a community with bbPress and Paid Memberships Pro. I’ve come across an issue I can’t fully explain or resolve:

Whenever a user with the bbp_blocked role tries to access bbPress content, they get a 404 page instead of a “you don’t have permission” message or a redirect as expected and set in PMPro.

These particular users are not suspended but free members without access to the bbPress sections of the site. I understand the bbp_blocked role is meant to restrict forum access, but why does it result in 404s rather than a proper restriction notice?

My specific questions:

1. Is it intentional that bbPress shows a 404 for bbp_blocked users?

2. If so indeed, can this behavior be changed to show an “access denied” message or redirect instead?

3. Is the bbp_blocked role actually meant only for moderation (bans), and not general access control?

Since I haven’t been able to find anything like my specific setup, any clarification or guidance is much appreciated before I start remapping roles or overriding behavior.

Thanks much in advance!

[John James Jacoby]

Hi @hardel 👋

I’ll take another look at this.

Is it possible you may have a work-around activated as a plugin that might be interfering, now that bbPress 2.6.14 includes its own fix?

[John James Jacoby]

This is also fixed directly in bbPress 2.6.14

[hollandnumerics]

1. Yes
2. Yes
3. Yes
4. The HTML in the topic is too large for this forum, and fails to save in a topic AND in a page using Classic Editor

I now suspect this problem is caused by Classic Editor, and not specifically bbPress

[hollandnumerics]

I have 1 success to report thanks to your WP_DEBUG suggestion:

• There were error messages being generated by bbpress Simple View Counts in debug.log, so I deactivated the plugin, and now the critical error messages are no longer seen when viewing topics.

The saving of updates to large topics containing table tags is still not working.

Not sure if these are relevant, but I’ve seen these messages about null parameters in functions.php:

[06-Jul-2025 14:51:35 UTC] PHP Deprecated:  strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /var/www/html/wp-includes/functions.php on line 7360
[06-Jul-2025 14:51:35 UTC] PHP Deprecated:  str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /var/www/html/wp-includes/functions.php on line 2195

Any assistance will be gratefully received, as my PHP knowledge is limited.

[hollandnumerics]

However, in Troubleshooting Mode, updated topic “test 3” is being shown correctly.

Active plugins: bbPress and bbp style pack

[titice]

No it is not theme related. Just decided to install BBPress plugin on my website and get same criticall error. Unpublished every plugin, except BBPress and activated default theme 21. Same problem – critical error.Version 2.6.14

[hollandnumerics]

FYI in issue #1 the post, when viewed, is empty whether the body contains table tags or not:

test 1:

hello

test 2:

hello

This is in Troubleshooting Mode with only bbpress and bbp style pack active.

[Robin W]

Does this occur anytime you try and access the forum page?

if so, it could be a theme or plugin issue

If that doesn’t work, also deactivate all plugins apart from bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

[watbos]

Upon update of bbPress plugin followed by activation, my user forum returns Critical Error. Thank you for any help.

Website: clubposh.com

Hosted at Hostgator
Wordpress version: 6.8.1
bbPress 2.6.14
Theme: OnePress Child (a child version)
PHP version: 8.3.6

[hollandnumerics]

Sorry, I will go back to just “bbPress” and “bbp style pack”, which currently shows the body “This topic is empty”.

However, my original issue with “There has been a critical error on this website.” occurred when the only users that could read this page were in Group5 = VIEWS UK, so maybe we should both add “bbP private groups” too?

Are you using Troubleshooting Mode to restrict the active plugins like me?

[Robin W]

ok, I’m a bit lost as to what your testing is showing.

The essence of fault finding is taking a setup that works and finding the difference between that and one that doesn’t work.

so I have a test site working with bbpress and style pack and nothing else. If your site with that same setup doesn’t work, then we can find the difference.

If it does work, then yes adding back plugins until it fails is a good strategy, but until we are both seeing the same, then it is not doing much good?

[Robin W]

ok, so this on my test site with just bbpress and style pack, using admin and keymaster roles publishes fine

<table>
<tbody>
<tr>
<td>
hello
</td>
</tr>
</tbody>
</table>

do you still get a critical error with this combination, and if so I still need the exact error it produces

[hollandnumerics]

Sorry, I missed Keymaster for Forum Role.

Plus extra plugins added, but no change to what is seen when viewing the topic:

bbPNNS Private Groups Bridge
bbP private groups
GD bbPress Tools
powerSearch for bbPress

[Robin W]

so in dashboard>users you will see a column showing the bbpress role

[Robin W]

ok, but what about the bbpress role?

[hollandnumerics]

Wordpress membership levels:

Free = Subscriber
Programming = Student
Recruiter = Employer
Admin = Administrator
Educational Games = Customer

Wordpress roles:

Subscriber
Student
Employer
Administrator
Customer
Keymaster
Participant
views_subscriber
views_student

bbPress Private Groups:

Group1 = Registered
Group2 = Programming
Group3 = Recruiter
Group4 = Admin
Group5 = VIEWS UK
Group6 = Educational
Group7 = No messages

[Robin W]

what are your wordpress and bbpress user levels?

eg

admin and bbp-keymaster
Subscriber and particiapnt

etc

[hollandnumerics]

• I have tried Troubleshooting mode, with no active plugins.
• Activated bbPress, then bbp style pack.
• Topic “test 1” now displays, but body shows “This topic is empty”, even though the HTML tags are seen when the topic is edited.

Do I need to activate more plugins?
