You need to update your config.php file.
It’s just $bb->uri
that I have to update, right?
Can you link to the subdomain and copy your config.php to http://bb.pastebin.com/ so I can have a look please?
For some reason bbPress seems to think your theme is in root. I’d ask you to set the theme again, but, you know, what with not being able to log in …
so first of all, please add define('COOKIE_DOMAIN', '.llamaslayers.com');
to your config.php. Hopefully that’ll let you log in.
It doesn’t do much of anything to add define('COOKIE_DOMAIN', '.llamaslayers.net');
or define('COOKIE_DOMAIN', 'llamaslayers.net');
to the config.php file.
Edit: It works to remove the values of $bb->wp_home
and $bb->wp_siteurl
