Clicking on a user’s name does not redirect to the profile

Hi! I’ve installed a comment plugin called “WPDiscuz”, but two things happen:

– If you are registered, it redirects you to your own profile, and not to that of the user you have clicked

– If you are not registered, clicking on a user takes you to the home page

I have contacted them, but they have told me that I have to speak with you, I am attaching a page where you can see it

The page I need help with: [log in to see the link]
