BuddyPress.org

wordpress 3.3.1 download from wordpress.org.
buddypress installed – from himself wordpress (plugin, add new)
bbpress installed – the same way, and from buddypress (installed main forum)

I twice deleting wordpress and installed. the same result

If activate usual links (addres pages) – then working bbpress. (buddy – links not work)
If activate permanent link – bbpress not open pages, buddy – pages open, but write “delete page”, or not open pages.

.htaccess contents

# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

My problem similar
https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/bbpress-global-forum-and-buddypress/
https://bbpress.org/forums/topic/bbpress-20-forums-page-within-buddypress

they advise
“well they don’t work well together so you need to hack it together”
“All I had to do was add [bbp-forum-index] in the proper page and there you have it.”

But what it is? where add the code? On what page? in what place?
sorry for my stupid questions.

as many other problems wait, in the future, from combination bbpress and buddypress?
