wpDiscuz comment plugin is designed for single post types (posts, pages, etc…). There is no way to load wpDiscuz comment form on Archive pages like category, tags, author, etc… 

Even if you find a way to include the comment section, it’ll not work correctly. The comments will be messed, i.e. the comments from one post will be added under another one. No matter under which post is made, a new comment, it’ll be added for only one post.

I mean comments for each post should be displayed on the post archive page , users need not to go to single post page to view or post new comments
