@biorm I solved my problem. Who knows if its the same as yours. What occurred in my case is bbPress for some reason changed the admin role to “none”. I was able to log in with a different admin account I’d previously established and change the admin privileges back to “Administration”. Unless you have another account on your wp installation with Admin privileges, I don’t know how to advise you. In any event, that’s the issue.
I’m having the same problem. WP and BB have their own directories… not commingling files.
