Ran into the same issue of 404 Not Found after activating BuddyPress on my WP installation on Ubuntu 9.10. Looks like the default Apache installation didn’t have mod_rewrite enabled.
To address this I did the following:
– sudo a3enmod rewrite
– sudo apache2ctl restart
– put .htaccess in my WordPress directory (/var/www) :
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
– put the following in /etc/apache2/apache2.conf
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride all
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride FileInfo Options
Order allow,deny
allow from all
</Directory>
I haven’t tested to see if this is all needed or not, but that’s what my site has configured now and it appears to fix the issue.
