BBPress in twenty sixteen theme

Hello,
I’m trying to build a wordpress site which acts purely as a forum. I am using the twenty sixteen theme, I loaded bbpress and I got the opening setup but I can’t add an option to register or retrieve lost password. I tried adding it to the widget as well as using wordpress tweaks, none of it worked. In addition, for some reason the login suddenly switched to text, [bbpress login], instead of showing the login box which used to be there. My site is forum.campexpo365.com. Thank you
