Hey Peter,
Have you tried enabling the Unfiltered MU plugin in the blog in question before you imported your posts?
Burt’s solution applies only to BP components, so if you’re not using object or embed tags in any BP component don’t worry about it.

Sorry, details are:
1. Which version of WPMU are you running?
2.8.4
2. Did you install WPMU as a directory or subdomain install?
Directory
3. If a directory install, is it in root or in a subdirectory?
root
4. Did you upgraded from a previous version of WPMU? If so, from which version?
Yes, 2.8.1
5. Was WPMU functioning properly before installing/upgrading BuddyPress?
Yes
6. Which version of BuddyPress (BP) are you running?
1.0.3
7. Did you upgraded from a previous version of BP? If so, from which version?
Yes, 1.0.1.
However, I could not get the auto upgrade function to work through the WPMU plugins browser, so I manually deleted all the BP1.0.1 and installed BP1.0.3.
BP1.0.1 was working correctly before installing BP1.0.3.
8. Do you have any plugins other than BuddyPress installed and activated?
No
9. Are you using the standard BuddyPress themes or customized themes?
Standard
10. Have you modified the core files in any way?
No
11. Do you have any custom functions in bp-custom.php?
No
12. If running bbPress, which version?
Not running
13. Please provide a list of any errors in your server’s log files.
Error log is empty.
Crap! Okay, I spoke too soon. When I posted the above reply, I received a blank page. But, at least the “strong” tag inserting issue has been “solved”.
Well, it seems that the tinyMCE (or whatever Javascript WYSIWYG Editor these bbPress forums were using) may have been causing the issue. It has been removed from the posting and editing panel and now I have no issues–especially the really annoying “strong” tag inserting issue that WebKit-based browser users experienced.
I can live without the convenience of quicktags. I’m very glad that I no longer have to deal with the “strong” tag issue.
Thank you for the response! I’m a total newbie at buddypress/wordpress mu/bbpress. Would you be able to provide some additional details as to how I can accomplish the 2 suggestions you provided, so I can head in the right direction? I’m not quite sure where to start. I’m using the bphome/bpmember themes.
Hello accentix,
Yes, 1 wpmu-buddypress installation = 1 social network. But each new member can add blogs as subdomain (or subdirectory).
I think the white pages identify BuddyPress as giving users a clean slate; something that can easily be built upon.
“BuddyPress: Bear friendly, and no regrets.”
LOL I actually got a white screen when I went to post this. 
My guess is it’s a server/user issue; probably getting overloaded as BP becomes more popular. I know that Google is probably indexing the heck out of it, because Googling my name comes up with a TON of BP links.
At lriggle; Your first issue sounds more like a cookie issue between BuddyPress and bbPress. Logging through bbPress isn’t giving you the correct cookies for WordPress/BuddyPress to recognize you as logged in. You’ve got some kind of one-way communication going on, and that can be hard to track down. Start by checking your bbPress integration settings and go from there?
The second issue is just a login screen thing. If you click the login link on the buddybar anyways, it will just direct you to the WordPress login page, which will dump you back at the blog root by default. There are other redirection plugins for WordPress and WPMU that will help with this.
Yep, see my “UPDATE” section in my post above. I brought this to Andy’s attention yesterday. He said he would pass it on.
But, I kind of like the white pages. It makes you feel like you are being kept from seeing something secret! 
Perhaps it should randomly change the screen color just to add some flavor–black, blue, orange, red or even clear!
Aye; it’s happening for everyone all the time randomly. My guess is the appropriate people wearing the right hats are already working on it.
P.S. – All browsers; Vista 64, random white screens fixed by refresh. Happens with all actions (posting, editing, and just viewing pages and posts.)

…also in my own WPMU (2.8.4) install with the latest BP trunk (1696).
The blank-page issue is specific only to these forums (BuddyPress.org/forum/…). Several of us are running the latest Leopard and Safari versions and often run into this issue after posting a reply to a thread. It seems to occur less frequently when accessing the main forums page.
As far as we can determine, it does not show any tendency to be more prevalent in one browser versus another. It also occurs for at least one of the BP moderators who is on a WinTel machine (for him both in IE and FF).
If anyone else is currently experiencing this issue, please post a quick reply here. Include your OS, browser, and noticed behavior.
UPDATE: I just logged out of BP and was redirected to a blank https://buddypress.org/ page. So, it is not a bug that only logged in people see and it is not restricted to the forums. I did suggest to Andy that the server(s) be rebooted as an easy first step. Sometimes that is all it takes. But, I think BP.org is split between several (how many) servers. I’m not sure what else may share that space. So, it may not be as easy (or at least as convinent) as I would think.
It loads fine for me with Mac OS X 10.5.8 and Safari 4.0.3, also in my own WPMU (2.8.4) install with the latest BP trunk (1696).
Hi Jeff,
many thanks for confirming ! So I do know now that it´s not an issue I am having myself only.
I just had the issue when I was trying to load the main page at URL http://www.buddypress.org
Best regards,
Erich
Created a ticket: https://trac.buddypress.org/ticket/943 (thakns for the searching, DJPAUL)
The Unfiltered MU plugin works for admins and editors in WordPress, but it depends what BP component you’re trying to use the embed/object tags in BP.
The Unfiltered MU plugin did not work for importing blog posts anymore. I needed a way to import 180+ post, most of them with embedded video on Blip.tv.
Yes, security is important, but if it wipes out 80% of my blog something’s gotta give.
I’ll remove the code from kses.php and let the Unfiltered MU plugin take over for just the main blog. Or wouldn’t that work? Would I have to start all over again, manually remove 180+ messed up posts?
How can I turn the object/embed tag stripping off in Buddypress’ main blog? I’m not trying to use the tags in a Buddypress component, only in the main blog. Or is that a component as well? Confused…
Like Zenseeker, I couldn’t make sense of Burt Adsit’s solution.

Please read this entire thread. Also, as referenced in that thread, these two tickets in Trac apply:
https://trac.buddypress.org/ticket/775
https://trac.buddypress.org/ticket/823
We are aware of the problem. Andy is looking into it. It occurs in all browsers and on both Mac and WinTel platforms.
For me, the issue is most prevalent after posting a reply. The proper URL for the thread shows in the address bar of the browser but the page is blank. As you say, refreshing the browser “solves” the problem.
Ok found the answer:
In bp-core.php change the ID inside
/* Define on which blog ID BuddyPress should run */
if ( !defined( ‘BP_ROOT_BLOG’ ) )
define( ‘BP_ROOT_BLOG’, 5 );
for the blog ID it should run on..
Thats it! ( Not found any problems yet )
Yes. Changing that bit in kses.php will let anyone use those tags almost everywhere on the site, so you’ve been warned.
There’s a reason why the embed and object tags are disabled by default, Peter.
If you’re going to open up your BP network to any user, they can potentially exploit those tags and do all kinds of nasty stuff.
The Unfiltered MU plugin works for admins and editors in WordPress, but it depends what BP component you’re trying to use the embed/object tags in BP.
Burt’s solution is the preferred method.
This is probably going to sound stupid, but I copied and pasted the example code from the readme and (as it is late) I did not notice there were single quotes around the whole thing. Not sure why they are there but I ended up grabbing the bottom one unknowingly and it took me a bit to realize it was why I was getting a parsing error.
But now all is well and as soon as I can find a bbPress version of the default buddypress template I am golden.
Thanks for this it is a huge help to provide integration.
Solved it by adding the following under ‘allowedposttags = array’ in kses.php:
'object' => array (
'id' => array (),
'classid' => array (),
'data' => array (),
'type' => array (),
'width' => array (),
'height' => array (),
'allowfullscreen' => array ()),
'param' => array (
'name' => array (),
'value' => array ()),
'embed' => array (
'id' => array (),
'style' => array (),
'src' => array (),
'type' => array (),
'height' => array (),
'width' => array (),
'quality' => array (),
'name' => array (),
'flashvars' => array (),
'allowscriptaccess' => array (),
'allowfullscreen' => array ()),
'script' => array (
'type' => array ()),
