It looks like you are trying to install BuddyPress under single-user WordPress.
BP currently requires the multi-user version of WordPress. Read this and follow the link in point one: https://codex.buddypress.org/getting-started/installing-buddypress/
This is the code for the right bar:
<div id="right-column">
<?php if ( !function_exists('dynamic_sidebar')
|| !dynamic_sidebar('right-column') ) : ?>
<div class="widget-error">
<?php _e( 'Please log in and add widgets to this column.', 'buddypress' ) ?> <a href="<?php echo get_option('siteurl') ?>/wp-admin/widgets.php?s=&show=&sidebar=sidebar-3"><?php _e( 'Add Widgets', 'buddypress' ) ?></a>
</div>
<?php endif; ?>
</div>
This is the code for the left bar:
<div id="left-column">
<?php if ( !function_exists('dynamic_sidebar')
|| !dynamic_sidebar('left-column') ) : ?>
<div class="widget-error">
<?php _e( 'Please log in and add widgets to this column.', 'buddypress' ) ?> <a href="<?php echo get_option('siteurl') ?>/wp-admin/widgets.php?s=&show=&sidebar=sidebar-1"><?php _e( 'Add Widgets', 'buddypress' ) ?></a>
</div>
<?php endif; ?>
</div>
This code is taking from the bphome theme…I believe it should work in your member theme, but haven’t tested it.
Also check out the bp-dev widget plugin which adds new widget areas for your member theme:
http://bp-dev.org/download/
You only need the bp-dev core and bp-dev widget from that list though. I hope that helps get you in the right direction.
Im getting the error when i try to install buddypress 1.0.3:
Warning: require(/wp-content/plugins/buddypress/bp-core-catchuri.php) [function.require]: failed to open stream: No such file or directory in /wp-content/plugins/buddypress/bp-core.php on line 25
Fatal error: require() [function.require]: Failed opening required ‘/wp-content/plugins/buddypress/bp-core-catchuri.php’ (include_path=’.:/usr/share/php5/’) in /wp-content/plugins/buddypress/bp-core.php on line 25
I contact the website support and they say:
You need to contact itself for getting the issue resolved.
I have no idea how this happened and could really use some expert advise.
Everything on the site was working perfectly until yesterday, and no plugins or changes were made to the site as far as I know.
For some reason http://anointed.net/index.php works but http://anointed.net/ returns ‘wrong host’. I also cannot reach any subdomain on the wpmu/bp install such as http://community.anointed.net which is the bp install blog.
I tried deactivating all plugins including buddypress but that made no difference.
I double checked the .htaccess file and it is indeed correct.
I checked directory permissions all are correct.
I checked the sites ‘virtual’ config folder and it is correct.
Really I have tried everything I can think of, but have no solution.
Has anyone ever run into this problem before with ‘wrong host’ when no filename.html is appended to the url?
thanks so much for any advice given. I’ll try just about anything at this point.
Hi, I had everything working on Darkpress theme, I then decided to switch back to the default theme and customise this, the home page works, but when on the members page, it seems there is no stylesheet.
I have latest versions of WordPress MU & Buddypress installed. (Installed only yesterday)
I also have “bpmember” folder in “wp-content/bp-themes/
EDIT: GOT IT WORKING!! THANKS
Thanks for the further comments Jeff.
I realise that the VIP service is for larger / select clients but sometimes us small time developers might stumble onto managing the next Facebook for a client and not be able to scale such a site quickly enough 
I have already explored some other avenues myself but maybe a BuddyPress site that could be considered high profile / having a great deal of potential could get Automattic to trial such a BuddyPress management service?
Will let you know whether this goes anywhere via the Automattic route!
Thanks for that Jeff. Disclaimers noted 
p.s. I got the server in a clearance sale… so the RAM was pretty low and there wasn’t an option to upgrade anything (as-is sale). It’s only $29/month though! Hard to beat for a dedicated box. And more than sufficient for the sites I’m hosting (so far). I don’t have unlimited disk space. All I have is what’s in the box… no upgrade options. That could be a concern if the WPMU users start uploading media files… but we’ll see. My freelance work may go full time within the year… so if that happens I’d bite the bullet and upgrade to a newer box anyway… and my client base would cover the costs.
Also, Automattic’s VIP hosting is provided to just a very few, select, large clients. It is not something you can simply decide to purchase.
So, my guess is that, yes, Automattic will offer BuddyPress installs to their very few VIP clients, but it will not be available to the vast majority of users.

I downloaded the zip file in March 2009. It’s 1.0 by the look of it.
Actually, you are using a pre-release version of 1.0. In fact, you are using the first release candidate (RC1). Before version 1.0 was officially released, there was even an RC2. So, you are five versions behind. There have been significant changes in the BP codebase since then.
As DJPaul states, do a backup of your Database (DB). Your MySQL DB files are stored in a different place than where you have WPMU and BuddyPress installed.
Also as Paul states, you will need to switch from /mu-plugins/ to /plugins. This is not an option.
Here are some detailed instructions. I would read these just so you know how things have changed since RC1.

As you say:
I know this is all very hypothetical and hard to judge…
So, given that as a premise, this is just my opinion. It seems to me that your current setup should be fine for what you’ve described. The physical memory seems low for a dedicated server, but you more than likely have sufficient virtual memory allocated to help alleviate some of that inadequacy.
The server’s physical HD space is not an issue since I assume that you have unlimited storage space with your dedicated hosting account. After all, hard drive space should be cheap.
When WPMU sites get to 1000 active users or so (or fewer very active users), many people find that they need a dedicate VPS or even dedicate server to handle just that single site. But, as I’ve said above, it depends on too many variables to accurately provide a detailed set of guidelines. One site may have little issues with several thousand users whereas another has issues at 500 users.
Okay… so what might be some example of server recommendations for different installations? For instance… I have a dedicated server but it’s not exactly high-powered. The specs are:
– 3.06 Ghz Celeron
– 80GB HDD
– 512 MB RAM
– 1000 GB Traffic
– 10Mbps uplink
Nothing fancy! But I’m only serving half a dozen small blog sites now with very low traffic. Mostly just small personal sites. It’s awesome for that and being dedicated allows me total control and I don’t have to worry about my ‘neighbours’ getting my IP blacklisted… etc.
Now… let’s say I launch a public BuddyPress site with 250 registered users, pretty low traffic from non-registered users, the bpPicture plugin, chat plugin, bbPress and NO personal blogs allowed (just the main blog). Is it gonna go boom? This client can probably afford to pay more for hosting if needed.
I have another potential BP project which would probably also be a low traffic site… but where the client wants users to be able to create blogs. It will be a true community site. It could have… let’s say 20-30 blogs. It would also have forums, photos and chat. This client is a friend. It’s a simple pro bono thing with no custom theming or coding. Problem is, she has no money for more ‘iron’. Not a cent.
I know this is all very hypothetical and hard to judge… but even a rough idea of server recommendations for a few different scenarios would be extremely helpful.
I’m currently working on a custom component and want to add the wire to it, so users can post messages.
The BuddyPress description (look here ) says the wire can be used with every component.
The question is: How?
Are there some special functions to use?
I think once answered, this would be a great addition for the skeleteon component.
Is there a widget that I can use that will pull the latest discussions from the forums (I’m using bbPress) so that they will display on the main page?
I’m using the standard Buddypress theme.
Thanks.
All this stuff that was going wrong after the 1.0.3 auto install:
The bad stuff:
4. The admin bar is missing when you click on someone’s profile and if you click to view a group. The admin bar is active everywhere else, including the backend of blogs.
5. Profile Wires and Forum Wires aren’t working anymore.
No buddypress plugins are active. Haven’t set any of them up yet. Just checking out the install. Not sure why wires aren’t working. hmm.
WPMU 2.8.2 + buddypress 1.0.3 + bbPress
On the wires of the profiles the Avatar is put in replace of the wire with an error message:
Warning: require_once(/home/mysites_org/htdocs/wp-content/bp-themes/bpmember/activity/activity-list.php) [function.require-once]: failed to open stream: No such file or directory in /home/mysites_org/htdocs/wp-includes/theme.php on line 843
On the wires of the “groups” a huge avatar is plucked out of nowhere and I’m getting this message:
Warning: require_once(/home/mysites_org/htdocs/wp-content/bp-themes/bpmember/activity/activity-list.php) [function.require-once]: failed to open stream: No such file or directory in /home/mysites_org/htdocs/wp-includes/theme.php on line 843
This was all fixed by uploading my backup from 1.0.2 of the wp-content – bp-themes – bpmember
There were some files missing from the 1.0.3 auto install that was causing the wires not to work, and the admin bar not to show up in places.
PROBLEM SOLVED!
Thanks to everyone for their very helpful tips!
Suprise, suprise! It’s running. I’ve installed WordPress MU in a folder in a folder and now it’s running. But don’t ask me why the root installation doesn’t work with buddypress in a folder.
Thanks Paul – I’m past that now – site is running but not fully functional and I’ve logged where I am currently in posts after this one.
Plugins have been turned off. Only buddypress is running.
Have emailed Paul – thanks!
When you are installing Buddypress, the only plugin you want in your /plugins folder is buddypress itself. Nothing in /mu-plugins either. Your plugins which run on buddypress are causing this error.
I have a few plug-ins running, but without the admin back end working, I can’t deactivate them. Can I place them in a separate folder temporarily without causing even more havoc? i.e. welcome pack, monty spam, wp ban, limited log in attempts, askimet, etc.
Email is probably going to get you a quicker answer. Only a couple of Automattic employees lurk here afaik.
Hi all
I am currently exploring various WordPress MU / BuddyPress hosting / mangement options for a client and wondering if there is anything in Auomattic’s plan’s to offer a similar service to the VIP Hosting that is currently offered for WordPress but for MU / BuddyPress?
I am just about to email Automattic direct but thought a post here might get a quicker response.
Cheers
I downloaded the zip file in March 2009. It’s 1.0 by the look of it.
Version number:
BuddyPress Version Numbers
Core: 1.0-RC1 / Activity: 1.0-RC1 / Blogs: 1.0-RC1 / Friends: 1.0-RC1 / Groups: 1.0-RC1 / Messages: 1.0-RC1 / Wire: 1.0-RC1 / Profile: 1.0-RC1 / Forums: 1.0-RC1 /
Readme was in the zip and can be found here:
http://coastalnet.co.uk/wp-content/mu-plugins/INSTALL-README.txt
What should my plan be to get the install running as currently intended? I’m a novice with database driven sites and PHP.
Fatal error: Cannot redeclare bp_activity_install() (previously declared in /home/mysites_org/htdocs/wp-content/plugins/buddypress/bp-activity.php:27) in /home/mysites_org/htdocs/wp-content/plugins/buddypress/bp-activity.php on line 101
Fatal Error after activating new install of Buddypress 1.0.3
The good stuff:
1. It sees all of the profiles.
2. It sees all of the friends.
3. It’s showing all the blogs recent activity.
The bad stuff:
4. The admin bar is missing when you click on someone’s profile and if you click to view a group. The admin bar is active everywhere else, including the backend of blogs.
5. Profile Wires and Forum Wires aren’t working anymore.

Just go to http://ww2.toksta.com and create an account and setup your chat the way you want it and click ‘Create Script’ and choose ‘WordPress’, upload it to the /wp-content/plugins dir and follow the readme file directions. It does work because I have it working on my site right now.

The plug-in does not working any more.
