Comment form visibility for a custom WordPress role

Hello wpDiscuz Support,

We are experiencing an issue with comment form visibility for a custom WordPress role.

Environment:

• WordPress
• Elementor Pro
• wpDiscuz
• Members plugin
• Custom role: k_member

Problem:
Users with the custom role k_member can see the comments area and are recognized as logged-in users, but the wpDiscuz comment editor/form does not appear.

Administrators can comment normally.

What we checked:

1. Comments are enabled on the post (Open for comments is checked).
2. wpDiscuz is active and working correctly for admins.
3. The custom role has the basic read capability.
4. In:
   wpDiscuz → User Roles and Badges
   the role k_member is enabled under:
   “Show comment form for post types”.
5. The issue occurs on newly created posts as well.
6. The user is logged in successfully and wpDiscuz recognizes the user name in the comments area.
7. We checked for obvious Elementor visibility conditions and did not find any.

Current behavior:

• Logged-in custom-role users see:
  “You are logged in as…”
  and the comments counter.
• But the actual comment textarea/editor is missing.

Question:
Does wpDiscuz require additional capabilities or configuration for custom roles created with the Members plugin?
Is there a known limitation or compatibility issue with custom roles and comment form visibility?

Thank you.
