.htaccess probably just needs to be 0644 permissions (-rw-r–r–). Did you set up permalinks with rewrite rules as described here? bbPress does not write the .htaccess file in the same way that WordPress does (i.e. when you change WordPress permalink settings, it changes or creates the .htaccess file for you, with the proper rules.)

Update: it looks like you are installing again? This page gives a 404:

This page shows that installation is not complete:

Once your installation is complete, you’re going to want to go here to create the rules which you will paste into .htaccess: http://www.greenfitnessworld.com/forum/bb-admin/rewrite-rules.php
