bbPress no longer uses the dropdown menu (what if your blog had thousands of users on it? It’d be really hard to find you!).

Instead, you should be able to enter your WordPress account’s login name into the form as you install bbPress.

But, there is a problem with your config.php

The values for $bb->akismet_key, $bb->wp_table_prefix, $bb->wp_home, and $bb->wp_siteurl should all be contained in single quotes (') like

$bb->wp_home = 'http://patrimoineacadien.com';
