I’m still having that problem. I tried all solutions on this page, but had no luck getting pretty URLs. Forum is working fine, but whenever I apply .htaccess settings, either copy-pasted from this forum or from rewrite-rules.php, I get an error

Not Acceptable

An appropriate representation of the requested resource /forum/topic/1 could not be found on this server.

Available variants:

* topic.php , type application/x-httpd-php, language ru

What could that be? I have the latest version of bbPress, it’s using wordpress database for authorization & authentication, but runs in a separate directory.
