And why does it call me “Deleted User”? What did I do wrong?
I see the same thing. I don’t know why it’s there, but what I would reccomend is going into your site’s dashboard, going to plugins, type in whatever plugin you want, and just make sure you add “buddypress” at the beginning.
At the top of the Plugin page, you should see a few different filters to view plugins:

I would bet that he meant buddypress.org plugin page , he sees only one plugin , I had the same problem with my Custom POST TYPE page , I saw only first POST , I think that it was related to permalink problems after update , when I have changed permalinks to default and immediately after to custom it worked again.
