Have you set this in your wp-config.php?
`
define ( ‘BP_ROOT_BLOG’, 2 );
`
(or whatever the site ID is)

I did not see that but added now.  If more multisite subfolder use bp-default theme do I have to add each ID like this:
define ( ‘BP_ROOT_BLOG’, 2 );
define ( ‘BP_ROOT_BLOG’, 3 );
define ( ‘BP_ROOT_BLOG’, 4 );
		
	 
	
	
	
 
		
			
	
	
		
		No, that’s just for switching which site buddypress runs on in a multisite install. If you want it to work on every site, use this:
define ( ‘BP_ENABLE_MULTIBLOG’, true );

Thank you for the “define”.  It works but bp-default theme does not obey site title for each site.  I try to change in super admin and still nothing.  Bug?
		
	 
	
	
	
 
		
			
	
	
		
		Probably! Submit a report on http://trac.buddypress.org so someone can check it out, thanks
		
	 
	
	
	
 
		
			
	
	
		
		define ( ‘BP_ENABLE_MULTIBLOG’, true );
This didn’t work on my sites and I’m still getting the same errors described above but the define ( ‘BP_ROOT_BLOG’, 2 ); worked for the single site. Any ideas? You prob need more info…haha
		
	 
	
	
	
 
		
			
	
	
		
		If you’re trying to use BP-Default on the non-BP_ROOT_BLOG site, and BP_ENABLE_MULTIBLOG (which is a mysterious parameter at the best of times) doesn’t fix it, I suggest you edit header.php in your child theme and set the links directly (remove the calls to site_url(), IIRC).
