Thank you for your answer.
That’s not the case and that’s my problem. I have access to WP admin panel, but only for Topics and Replys. To be sure I made a new local site with just WordPress and BBPress installed, one user Keymaster and it’s the same thing, not any forum panel. I’m running the french version of WP and BBPress, I don’t think that changes something but I’m gonna try with the EN version to be sure.
