Re: Redirection to new bbPress board?
You mean to just redirect one folder to another?
Delete the phpbb2 folder and in your .htaccess add this:
RewriteRule ^phpbb2(.*)$ http://www.domain.com/bbpress/ [L,R=301]
That will make what’s called a Permanent redirect, and in theory teach site crawlers what’s up. Mind, a 401 is for unauthorized access, which is an odd error to get.
