BuddyPress.org

On every tab Activity,Profile etc I get page not found on the title tab. I have already set my permalinks as http://www.example.com/example-post-blah. Everything else seems to be working fine.

Here is my wordpress section on my .htaccess file.
# BEGIN WordPress
# The directives (lines) between BEGIN WordPress and END WordPress are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Am I missing anything ?
