further update… I installed & activated the “Enable bbPress for Block Themes” plugin as suggested by @robin-w and there was no change wrt the subscribe/unsubscribe functionality. Of note, the forums do function normally, and always have, in my configuration. It’s just the subscribe/unsubscribe function that is broken

[Danny89]

I’m actually looking into this as well 👀

I’m planning to convert my existing WordPress site into a full forum using bbPress, and the classic/default theme setup is something I’m trying to understand better.

From what I’ve gathered so far, it seems like the process is:

* install and activate bbPress plugin
* create forums from the dashboard
* then adjust the theme (or use a child theme) to make it look more like a proper forum

I’m still a bit unsure about the best way to properly switch or enforce the “classic” bbPress layout across the site.

Would love to hear how you approached it — especially if you managed to fully convert your site into a forum-style experience rather than just adding forums as a section.

Thanks! 👍

[Robin W]

I suspect you are using a block theme also known as “Full Site Editing” or FSE theme

This is one of the “block themes” – this is the new way that WordPress plans to develop themes. BBpress authors are working on a fix for this, but in the meantime, add this additional plugin

Enable bbPress for Block Themes

Come back if this does not work

wordpress.com couldn’t resolve my problem and they shorn me over to the bbpress.org website to handle the problem … i want to do a bbPress forum on that website but i can’t get it started and wordpress doesn’t know why we tried a different theme and that didn’t work … i uninstalled all the plugins and that didn’t help … i checked the root directory and made a change to it and broke it and changed it back and got back to square one so i think the root directory is fine … i couldn’t and can’t reset the permalinks because i’m not at that level yet on wordpress … this occurred directly after installation and i created a forum and it went to the white screen when i checked the permalink and then i started a topic and that permalink went to the white screen … i’m just a writer this is already too much code for me to handle

so if anyone knows anything about this let me know …

Hi there,

I’ve only just started using bbpress and still learning how to use it.

Is there a way to restrict a certain user role to one forum only? In other words, they can only view topics and replies in that forum.

Thanks in advance.

[craftylion]

I’ve just installed the latest version of bbPress and I’m having a little trouble solving this. I’m running a test site and would like to edit my profile frontend. The only problem is, I can’t see the text to know what I’m typing (the text is white on white background).

Any thoughts?

[Robin W]

If you are using the Divi theme (or a child theme of this theme) and have an issue whereby bbpress Profiles and bbpress search may not work properly

If you have issues with either of these, please change the following Divi theme settings:

1. In Dashboard> Divi> Theme options > Builder > Advanced > Static CSS File Generation > Clear

2. In Dashboard> Divi> > Theme Options > Performance> Dynamic CSS option> set to Disabled

3. THEN critically you need to clear any server side caching AND clear your browser cache.

Server side will depend on your host, and/or any caching plugins you have installed

For your browser – see this helpful article How to clear browser cache

I disabled the search functionality for now, but the link in my post still showcases what’s happening with the upper part of the page. only the result is not the bbpress forum result annymore.

[gielvankuijk]

Hi,

I’m running the latest bbPress with Divi 5 as parent theme and a basic child theme.

My forum root page (/forums/) renders correctly using a Divi Theme Builder layout.
However, the following bbPress routes break the layout:

/forums/search/
/forums/users/username/

They load, but the page structure is incorrect. I get a large white space and weird styling of the logo and menu in sidebar. The forum is for users only but you can see an example here: https://beterbeleggendandebank.nl/forums/search/test/

I tried serveral fixes but nothing seems to work. Does annyone have experience with this or a similar issue and has a solution?

Thank you in advance!

[Robin W]

some great fault finding carried out there, many thanks for that.

To start at the end, twenty twenty five is a FSE theme and pending the next release of bbpress you need to add

wordpress.org/plugins/enable-bbp-block-theme/

It looks like you have an issue between Highend Theme 1.0.2 and buddypress, which might be difficult to get resolved.

As highend is a paid theme, I cannot check it out, but I would start by asking them, as you can show it working with a wordpress default theme, but not with highend#

Hi,

Every day at same time, I can read PHP fatal error, concerned with 2 plugins:

BBPress for a forum with very few articles and comments,

WP-Optimize, for page cache and image compression.

No idea where it comes from. No cron at that time….

Every thing is up to date: WP6.9.1 PHP 8.3.30, all plugins with automatic update.

Thank in advance for helping

I wrote this thread, maybe it might be useful to you.
Hi

SEO Index Forum

[davidqutta]

If you’ve already unchecked “Allow topics to have tags” and the tags field is still appearing, it’s usually caused by one of the following:

First, clear all caching (plugin cache, server cache, and browser cache) and then refresh the page. Sometimes the old form layout is being cached.

If that doesn’t fix it, temporarily switch to a default WordPress theme. Some themes override bbPress templates and manually include the tag field, which makes it appear even when disabled in settings.

Also try disabling other plugins briefly—especially SEO, forum add-ons, or customization plugins—to check for a conflict.

If the setting still doesn’t apply, go back to Settings → Forums, enable the option, save, then disable it again and save once more. Occasionally the option doesn’t update properly until it’s re-saved.

If none of that works, it’s most likely a theme template override forcing the tag field to display.

Hello bbPress Support Team,

https://oudmajlis.net/forum/

I am having an issue with my bbPress forum on my WordPress site. When I try to open the forum, it displays a blank white page.

I also received a warning about a potential slug conflict:
“Potential bbPress conflict: Forum slug”

Here is what I have tried so far without success:

Changing the forum slug

Deactivating and reactivating bbPress

Checking for conflicting pages or posts

Flushing permalinks

Clearing browser and server cache

The forum contains important data (topics, replies, users) that I cannot afford to lose.

Could you please advise how to resolve the blank page issue and the slug conflict safely while keeping all forum data intact?

Thank you very much for your help.

https://oudmajlis.net/forum/

[Robin W]

ok, so what theme are you using?

and which method in

https://codex.bbpress.org/step-by-step-guide-to-setting-up-a-bbpress-forum/ part 3

are you using?

[pashalyndi]

Hi All,

I’m a newbie here, but willing to give it a go!

Setting up a simple forum.

Need help, there is not adequate padding/line breaks before the bbPress plugin.

So the ‘Subscribe’ button gets chopped off at the top.

Wish I could post an image or link for you, but the forum is members only.

Have tried this in the theme Customize CSS section:

BBPress Top Margin:

.bbp-the-content-wrapper {
margin-top: 16px; */
}

.bbp-submit-wrapper {
padding: 16px 0;
overflow: hidden; /* Fixes container issues */
}

Thanks in advance, your help massively appreciated.

Warmly, Pasha

[manojmohandev]

I’ve noticed some strange behavior and I’m not sure if it’s intended. When a topic is approved after being sent to moderation, and the user subsequently edits that topic, the revision log displays two revisions instead of one. Ideally, the log should only display the specific edit the user marked for logging, rather than all revisions.

I found this line of code which appears to accept any revision, including those not typically found in the bbPress log. Ideally, it should skip any IDs that are not explicitly present in the bbPress log.

[Robin W]

ok so I now have 2 different things

1. clicking profile goes to the users own profile
2. clicking profile says sorry you are not logged in

Without a consistent problem definition it is hard to help, but as stated above, clicking someone’s name should take the user the that person’s profile.

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

[Robin W]

quick response, I’m a UK farmer, so out a lot of the daytime !

As a ‘quick and dirty’ solution you would need to create the topic

Then in a new item I’ll add in the dashboard enter the post ID and the Topic ID

This will then create a new reply.

It will keep the existing comments.

from memory bbpress uses ‘anonymous’ for any user that no longer exists, but if you create a ‘deleted user’ I might be able to add that to the code

[Joakim Nömell]

Thanks, Robin — that would be absolutely fantastic!

With a smooth and simple solution like that, I could even consider importing 3–4 more posts that originally were discussion posts and would fit much better in the forum. But no larger volumes than that.

I don’t know exactly how you’re planning to solve it, but if possible, it would be great to keep the original post and its comments intact until everything is confirmed to be working. If it’s easier to convert the existing content directly, that’s perfectly fine as well.

In our system, users also have the option to delete their own accounts if they wish. I assume we therefore need to take into account that some users who commented may no longer have a valid user ID. In that case, I guess a fallback user is needed? I do have such a user in my system called “Deleted User,” whose user ID could be used if necessary.

I’m also not entirely sure how bbPress handles topics and replies when the original user accounts are deleted — I haven’t had a chance to test that yet. 🙂

Many thanks for your help. I really don’t have the required level of knowledge for this, so it’s very much appreciated. 🙂

[Joakim Nömell]

Thanks, Robin — much appreciated.

Unfortunately, no, I’m not comfortable with code, and definitely not at that level.

With the plugin you’re suggesting: am I correct in understanding that it does not import existing comments from the original post as replies in bbPress? What I would really like is to move all 78 comments over as replies in the bbPress topic, and ideally be able to delete the original post entirely afterwards.

I’ve already created the topic itself manually in the correct forum, preserving the original text, date, and author. The only remaining (small 🙂) problem is the replies. And since those 78 comments contain a lot of valuable content, it wouldn’t feel right to start over from scratch in the forum.

[Robin W]

Ok, I am just a volunteer who helps out here, I am not a bbpress author, but I have written a number of bbpress related plugins.

I also took over a defunct plugin called

Post Comments as bbPress Topics

I did not write this, I just did enough coding to get it working again.

if you are code savvy, then function build_topic on line 485 of index.php should give you some code that you could maybe use in a plugin or use the code snippets plugin.

otherwise if you only have a few posts from which you want 2, you could enable it convert, disable it and then delete the topics (posts) you don’t want.

[Joakim Nömell]

Hi. I don’t get any chance to enter a topic ID. The page crashes as soon as I click “Add New Reply”, and the form never loads at all.

I agree that normally there’s no real need to create replies via wp-admin. The reason I want to do it in this case is to paste content from comments on a regular post, in order to move an existing discussion into bbPress (see my other thread about importing individual posts and comments into bbPress). From the admin side it would be easier to create replies, attach them to a topic, change author and date, and paste the original text.

It is possible to do this via the frontend and then edit the replies in the backend, but that adds several extra steps. Also, since the “Add New Reply” function exists in wp-admin, I assumed it should work — and it didn’t feel right that the page crashes instead. 🙂

That said, if there is a more automated or cleaner way to import posts and their associated comments into bbPress, that would be much better, and in that case I wouldn’t really need to use Add New Reply in wp-admin at all.
