In a fresh development instance I went to http://localhost:3000/mod and got a 500 Server Error related to

ActionView::Template::Error (No route matches {:action=>"new", :controller=>"posts", :post_type=>nil}, possible unmatched constraints: [:post_type]):
    34:     <div class="widget">
    35:       <div class="widget--body">
    36:         <i class="fas fa-file-alt"></i>
    37:         <%= link_to 'Create Help Page', new_post_path(post_type: HelpDoc.post_type_id) %>
    38:       </div>
    39:     </div>
    40:   </div>

app/views/moderator/index.html.erb:37:in `_app_views_moderator_index_html_erb___3348426895881517021_62660'

How can I fix this?

It might be related to How can I add post types to a category?

P.S.: I redid the setup of QPixel and this error is not reproducible even though the db:seed error still is. Will close as "not constructive".

This is related to your other problem - it's the same root cause. Without any post types in the database, there aren't any to add to the categories, and the help and policy post types don't exist to make this link work.
