BuddyPress.org

Finally tracked this one down! OMG was it hard!

Basically, using /%category%/ doesn’t work in the permalinks anymore, if it ever did in the first place. That was my problem the entire time, and now I can safely rename my /blog to /news or /cheese or /beer or whatever…

Phew… Should this be tracked? I’ve confirmed this on a stock install of BuddyPress/WPMU also to confirm.

Also, that function you mentioned, basically bypasses archive.php, category.php, etc… And only serves up index.php and single.php…
