Resolved it. Sorry for taking your time.

The bbp-user-functions.php file exists and has the correct permissions, and the bbp-converter.php is currently located in the /bbp-admin/ folder.
Line 1466 is as follows : bbp_add_user_subscription( $subscriber, $destination_topic->ID );
Looks like I’m getting the following error:
PHP Warning: require_once(bbp-converter.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory in /home1/mojaveun/public_html/blog/wp-content/plugins/bbpress/bbp-includes/bbp-user-functions.php on line 1466
