One more bit of confusion here:
The readme states
VERY IMPORTANT: If you are no longer using the old two-theme system from BuddyPress 1.0, please make sure to delete your /wp-content/bp-themes/ folder to activate the new one-theme setup.
This conflicts with the error message, which says to move the new theme files to the folder that the readme tells me to delete.
I had to first upgrade wpmu to 2.8.4a (from 2.8.4), and then I no longer got the fatal error when I auto-upgraded the BuddyPress plugin. However, my site was blank. In reading the instructions about the themes, I saw that I needed to move files from /wp-content/plugins/buddypress/bp-themes. When I went to my server, there was no bp-themes folder there. Don’t know if something happened in the auto-upgrade or if auto-upgrade installs an incomplete version of the plugin.
I reinstalled buddypress, moved the themes from /buddypress/bp-themes to wp-content/themes (per the readme file), and I get this error message:
You do not have any BuddyPress themes installed.
Please move the default BuddyPress themes to their correct location (move /wp-content/plugins/buddypress/bp-themes/ to /wp-content/bp-themes/) and reload this page. You can download more themes here.
Note that the readme says:
move the themes in “wp-content/plugins/buddypress/bp-themes/” to “wp-content/themes”
while the error message says
move /wp-content/plugins/buddypress/bp-themes/ to /wp-content/bp-themes/
following the instructions from the error message does allow wpmu to recognize the themes–but I still have a blank site. One problem down, more to go.
add this to you custom style sheet
/* BuddyBar Removed - fixing gap */
body { padding-top:0px!important; }
From the post above mine “The biggest part that is not included with the current port is the directory view, since that was still in flux when I started porting so I left it till matured.”
Basically it sounds like Erwin will be taking over again to finish it up for BuddyPress 1.1. So we just have to be patient 
I’m sure it will be worth the wait.
Also, it’s super important to read this document before you attempt upgrading:
https://codex.buddypress.org/getting-started/upgrading-from-10x/
They are not stored in the DB, BuddyPress will look in the avatars folder under the user’s ID in blogs.dir.
I will try the upgrade again but will be EXTRA careful on the directions – I was in a hurry last night so perhaps I overlooked something…as soon as I get the results I will let you guys know!
Thank you for the responses.
I meant that it’s a plugin insofar as I dropped it into “/domain.com/wp-content/plugins/buddypress/bp-forums”.
As I said everything’s the latest version so:
WPMU – 2.8.4
BP – 1.1
bb – latest build from SVN
As for the theme, even if I wasn’t supposed to be using it, I was trying to change it. Problem is, it won’t change now.
I made all the necessary url changes in the database, and the rest of the site works fine. Also, the problem with the blank profile page for the members directory was happening BEFORE I moved it too.
I guess I will try dropping all the BP tables and reinstalling Buddypress, maybe I will get lucky… I’ve got my fingers crossed!
I made a pot file for this plugin and added code to translate the php file.
Where should i put the zip ?
A french version is already avaible on http://www.buddypress-fr.net
Buddypress 1.1 and the most recent version of WPMU… 2.8.4 i believe 
thanks!

@all : Now you can download updated plugin for BuddyPress 1.1
just to the home page of buddypress, like here:

Couldn’t this be posted on following topic?
https://buddypress.org/forums/topic/features-request-classifieds-plugin
I’m not sure if you can get enough response on problems on your own plugin.
Wow! Seems like it’s raining plugins right now!
Hi David, I have been very busy with a deadline at the office. Now with 1.1 out I am re prioritizing working on the BASE code for bp-events 1.1. Some stuff will need to be updated to reflect the gazillion bug fixes in BP 1.1. Eventhough it seems to work fine on my install, I will create another local install to see where it is at with the official BP 1.1.
My task has been really to port over the basic events functionality as a service to the community. Erwin will continue on this port and extend the features as he wishes. The biggest part that is not included with the current port is the directory view, since that was still in flux when I started porting so I left it till matured.
Give me some time as I also have another major plugin (group blog) that needs reworking of the code. However as I said, my aim is to help build a stable release for a bare bones bp-events 1.1. That is the most important task, upon which new features can be build.
Make sure to read the readme of the trunk as installation will be different and more compliant with buddypress methodology of installing plugins versus wpmu.
So…just a little more time or help is always appreciated
I see that you have double posted.
I’ve answered your question in this post
@Tore
That’s the proper attitude!
The forums are their own, separate plugin. I’ve already clearly explained the reasons why this component will not provide bbPress forum privacy filters. You are free to use any bbPress privacy plugins that you want. Perhaps in the future this will change, but right now, it will not be an option.
Network Parent Theme sounds like a custom, 3rd-party theme to me. The default parent/child BP themes are bp-sn-parent and bp-default.
Make sure that you have enabled the BuddyPress default theme in the “Site Admin > Themes†menu and then activated the BuddyPress default theme in “Appearance > Themesâ€.
If you’re still having issues, read the second linked to thread in my post above.
It’s sad to hear that the forums won’t be part of this. I’ll just keep on allowing no one into the website who isn’t a member. Thanks a lot anyway!
@lsddesign
Which version of BuddyPress are you running? Which version of WPMU?
I keep trying to select the Buddypress default theme and it says settings saved but the page then reverts back to showing the Network Parent Theme 1.1 as the default one. Is this correct?
@colly72-
Are you are using a custom theme? If so, please read this.
If not, then read this.
Holy crap! I thought that feature wouldn’t be in until some later version. This is great! Core!
I get exactly the same error, brand new install of WPMU 2.8.4a and Buddypress 1.1, no other plugins installed.
HEEEELP!!!
