Re: help please anyone…
sub-domain? did you mean add-on domain?
You just need to move (re-install) all bbPress files up a level. If you installed them into
mv public_html/konpaforum.com/bbpress/* public_html/konpaforum.com/
If you want to integrate into WordPress, then leave them and install WordPress in
public_html/konpaforum.com/, would be a good idea.
