It happened to a test site when I installed WP 3.2. Upgraded to WP 3.2.1 and BP 1.2.9 and all’s well. Do you have any error messages coming up on screen?
Well I don’t know if this a bug or not, but I found (almost) the root of the problem and a relatively simple fix.
I discovered that the recipients table had entries for threads that were not in the messages tables. I don’t know where these threads came from, but they were definitely there. So I changed the messaging code to generate the thread_id from the recipients table rather than the messages table.
If this was some sort of database corruption, this was a reasonable fix for me. We don’t have enough messages for it to be a performance issue and if something else is inserting into that recipients table we shouldn’t conflict with it (assuming it is generating thread_ids in the same way).
I really don’t know enough about BuddyPress to know if this is a core bug or some other issue related to our theme (I can’t find any other references to that table so it’s kinda wierd).
bp-messages-classes.php:
/* If we have no thread_id then this is the first message of a new thread. */
if ( empty( $this->thread_id ) ) {
$this->thread_id = (int)$wpdb->get_var( $wpdb->prepare( “SELECT MAX(thread_id) FROM {$bp->messages->table_name_recipients}” ) ) + 1;
$new_thread = true;
}
Thanks @modemlooper I know 
but will that uninstall and delete the groups tables from my database?
I still have the question, will bbpress plugin cause any conflict with buddypress?
Not sure how updated this is but… : https://buddypress.org/community/groups/buddypress-group-documents/ – more for groups though.
https://wordpress.org/extend/plugins/buddypress-activity-plus/ may also be something useful to you.
Whatever method you go it’s going to be a plugin route really to get that working for all you list.
Could you provide a link to your site please so we can see?
You should be able to see all members under the members tab however could depend on your theme and / or plugins you have along with your install.
Could you also please try using the BuddyPress default theme as that may be a good gauge – I understand if that isn’t possible?
in admin under BuddyPress components link you can disable groups component.
This buddypress installation here has some buggs bugging around for quite some time – impossible to edit post (try it!), search does not work etc.
Anyways, wanted to add a link to a plugin which might at least solve some of the issues (make sure you read the FAQs):

Hi, I have a wordpress site that has 760 members on it. I just added the BuddyPress Plugin and a BuddyPress Theme and when I click on Members, I only see me there. It says “760 Members” but only shows mine. Is there a way to make all my members show up there?
Awesome, thank you! I will look into this.
I may come back for a few questions
Hey Everyone,
I wanted to give everyone an update as to the troubles I was experiencing and how they were resolved.
First–the email problem seems to have been fixed with the SMTP plugin. Thanks again mercime!
The Parse error and warning message we were receiving have been rectified by a server-side fix. We run a VPS with Lunarpages and come to find out a component called suPHP was not installed (suPHP is apparently what shared servers run, and seems to be pretty important in ensuring the basic functionality in WordPress and Buddypress actually works by allowing web users to write to the directories without changing the directory permissions to the dreaded, unsecure 777). By installing and setting up suPHP in addition to running PHP 5.2.11, the parse errors, warnings, and image uploading permission problems have been fixed, as well our WordPress-writable file/directory permissions are functioning perfectly at 755 and more sensitive file permissions are at 644.
So overall, most of the fix was rooted in our VPS not running suPHP and needing to get it installed and configured correctly.
I hope this helps someone else out there experiencing the same problems as we were!
Hola I was happy when I heard about bbpress plugin lately, that what I have wanted from the start, and I’m happy I knew it before launching my website, I installed the built-in forum system coming with buddypress and created one group only for test, now the question is, how I can safely uninstall the groups system at all to install the bbpress plugin instead, and will installing bbpress cause any problem with buddypress?
I appreciate your time and help thanks.
@roman – As long as you are running BP 1.2.9, you shouldn’t experience the WPDB error described above.
There’s built in hooks to change slugs and other things.

hi, did the same stupid thing by mistake. updated to wp 3.2.1.
which is the best known way to just get back to the latest known as working version of wp?
thanks!
Would be the same as moving a WordPress site. because that’s what you have. 
Your new host will probably even move it for you. Good ones do.
Hi there, I am looking at moving my buddypress site from my existing crap server to a better one and another hosting provider, is there any guidelines for doing this and is there a way to lockdown activity so people can still see the site in a read-only mode whilst the dns changes take affect?
Thanks
Yes, I’ve enabled groups, and everything else works fine.
The theme is the latest version, and I’m using Buddypress Template Pack with the theme.
I’ve tried the default, and I have the same problem.
Where are my PHP logs located, so I can check them?
Thanks.
Those conditionals do not apply to activity comments.
The easiest way is to use CSS to hide the comment link.
The alternative is to copy the entry template into your child theme and edit:
/bp-default/activity/entry.php
As for nested comments, currently you’ll have to apply a filter to “bp_activity_recurse_comments” (located in bp-activity/bp-activity-templatetags.php):
https://buddypress.trac.wordpress.org/browser/tags/1.2.9/bp-activity/bp-activity-templatetags.php#L678
Don’t know anything about filters?
http://themeshaper.com/2009/05/03/filters-wordpress-child-themes/ (tutorial applies to themes, but also works for plugns; there are a bunch of tutorials on the web as well!)

This will get slightly easier to modify in BuddyPress v1.3 as activity comments now have a dedicated template file.
Try modifying the BP Activity Stream widget to do what you need:
http://buddydev.com/buddypress/buddypress-sitewide-activity-widget-for-buddypress-1-2-and-above/
It’s applicable for all activity, but it’s probably possible to hack it to work for your one group.
Hook into the filters or actions whenever possible. (Basically anywhere in the codebase with an ‘apply_filters’ or ‘do_action’ call.) Otherwise, you’ll run into major upgrade problems and headaches depending on the level and complexity of your hacks!
Need a primer on filters and actions?
http://themeshaper.com/2009/05/03/filters-wordpress-child-themes/
That tutorial is for themes, but applies to plugins as well.
Hope that helps!
Sorry, I’m a total newbie here and just learning how to build websites and using wordpress/buddypress.
My website is http://www.40knovels.com.
All of my internal pages outside of the main page come up as “page not found” 404 error. I can’t seem to figure out how to resolve this.
Any help would be great.
Site update still ongoing. @tnd, just include word buddypress.org with search terms when you Google.
My first thought would be what theme are you using? If not the default BuddyPress one try that if you are able and see if you get the same result.
It would probably help to get a little more information too please. What version of WordPress and BuddyPress are you using? If possible a link to you site too could help.
