I found this Sceen Cast from sambauers at Automattic on the BBpress forum which goes through the install of wordpress mu 2.7 and bbpress 1 alpha. The integration of wp and bbprees is also fully shown.
https://bbpress.org/forums/topic/basic-integration-screencast
That sounds ominous. I googled the phrase and found several forums (with WPMU) where people reported the same problem and gave some fixes. No one seemed to think it was that big of a deal.
As for me, my WPMU works fine until I add the buddypress plugin; then it stops working.
Anyone have any solutions?
it appears that wp look after my data base but it cann’t find it because it is not the good name.
I don’t know what i have to do :
-create a new database and copy the other into the new. (i’m not sure i’m able to do it)
-is it possible to change somewhere in wordpress the name of the database called by the application ?
Thanks for your help

Something is very wrong with your installation if you’re getting that error. That is a core WordPress function.
Here’s the Php error that I’m getting:
Fatal error: Call to undefined function wp_get_current_user() in /html/wp-includes/capabilities.php on line 920
Any ideas?
Thanks. So far, wordpress mu is working beautifully. It’s when I try to add in the buddypress plugin that everything goes wrong.
FusedNetwork, not the cheapest, but the best.
They set up everything I needed for WordPress MU, on request, very quickly. At the time I didn’t know what I would need to request from them besides setting up the wildcard masks, but luckily, they knew exactly what was needed.
Highly recommended
http://speakeasyesl.com/mu This is a testing ground for another wordpress install I’m thinking of for language learners.
@cikguazleen this is a problem with earlier versions of php 4. Can you get your host to get you on php 5?
Here is an explanation about error.

Ok…figured it out for dsader’s plugin. Just needs priority added to it. Check out this post in WPMU forums, but basically add priority to the template_redirects like:
add_action('template_redirect', 'ds_users_authenticator', 1);
add_action('template_redirect', 'ds_members_authenticator', 1);
add_action('template_redirect', 'ds_admins_authenticator', 1);
Just adding the “1” for priority makes it go before Andy’s changes. All those lines are near the top of the plugin.

Be careful on a shared host. WPMU shouldn’t really be run on anything less than a VPS. You might want to check your PHP logs.
I deleted the database table bp_core_widgets_welcome and then let BuddyPress/Wordpress rebuild it when I created a new welcome message. Works perfectly now.
Thanks, guys. Believe it or not there aren’t any errors in the log they provided. I’ve asked them to escalate a ticket to see if there are other logs, since I’m on a shared hosting plan.
Hello! I recently installed WPMU + buddypress to run a brand new community.
There is one feature we want to get working but I don’t know how to achieve it.
When you first run a WordPress installation it comes bundled with a default “About” page. Is it possible to make an installation where more default pages are created for our users like a “Portfolio” + “Profile” + “Blog” pages so htey don’t have to crate them?
It would be also useful to have the ability to deactivate permalink editing for those pages and the addition of more pages, but keeping access to the content editing of course; the aim is to make a Myspace-like site with the flexibility of having different pages in the site for every user but with the advantage of standarizing site layout through the entire community so the users concentrate on social connection and content publishing and not worrying them with themes and site structure stuff; It is an art oriented community so we want to give everybody the same basic features so they may share and connect within the community and publish their works to non-users/general public on their public WP sites.
Thanks in advance for any help 
Just to add, they will be the ones that say FATAL ERROR as well 
Did you wipe your database? The first 20 lines of your logs should be enough. Make sure you wipe anything sensitive.
I’ve gotten the php log files (still waiting on apache), but don’t know what to look for specifically. Any help would be appreciated.
@Trent, there is no error on the screen–it is totally blank.
This is the first anyone has asked for Apache logs (which I’ve requested from my webhost).
I only posted my question early this morning; when I said the response wasn’t satisfactory, I was referring to the other post which was never answered (and which may have helped me).
P.S. I had buddypress working at first, but deleted the blog by mistake. So I removed all the files from my server and reinstalled them and now they aren’t working (but WordPress MU is working fine). Does this help?
@jfcarter Andy has told you that you need to provide the error that you are getting. Check your apache error logs and tell us what the error you have. It could be many different things and is not a widespread issue, so we need to know the error. You haven’t had a satisfactory response yet because you haven’t given any information to provide such a response.
Trent
I’ve checked with my service provider to see what they can tell me. As I mentioned before, others are experiencing this and there hasn’t been a satisfactory response yet.
I have checked all my permissions, and my WPMU install is fine. It’s just the buddypress that isn’t working properly.
If you can’t check your logs or turn on error reporting then fixing this will be like finding a needle in a haystack.
Apparently this is happening to others, but no one has resolved it: https://buddypress.org/forums/topic.php?id=404
I did check the mu-plugins folder (it’s at 755) and it’s in /wp-content.
Did you check the permissions of the actual mu-plugins folder? Is the /mu-plugins folder in /wp-content?
When I type my domain, nothing comes up as long as the mu-plugins directory is there. Once I delete it, I can see the WordPress blog (but then I don’t have the buddypress stuff and themes). I don’t know how to check the logs or how to turn on error reporting in Php
