BTW I tried what was advised in this thread: https://bbpress.org/forums/topic/bbpress-broke-when-i-changed-the-url but it just displayed the code on the actual live forum page
Here is my bb-config.php included the added part at the very bottom:
<?php
/**
* The base configurations of bbPress.
*
* This file has the following configurations: MySQL settings, Table Prefix,
* Secret Keys and bbPress Language. You can get the MySQL settings from your
* web host.

* This file is used by the installer during installation.
*
* @package bbPress

I found the solution! I went under Settings > Permalinks and updates the .htaccess file with the information there.
If this happens to anyone in the future, check there
