several issues with the forum

Jack Porter 5 years
  1. when i click on a forum i created it goes to a blank page. 
  2. when i click on 'new topic' nothing happens. (i had to create a topic from the backend). 
  3. no reply buttons to topics.
  4. when user's register it leads to a blank page.

is this compatible with WP 5.6?
