Installed bbpress successfully on personal WP blog. No problems.
Attempted install on second blog and I get an odd error when trying to access admin. After entering keymaster name/password and clicking login, I get redirected to:
(WP plugins folder now seems a weird place to install, but I was just jumping in)
The redirect address just takes me to a “not found” page on the WP blog. So, I go back to the initial /bbpress/ location and the keymaster name shows as logged in. All links appear to function fine except for Admin. Clicking on this does nothing.
