Hi,

I'm having an issue where registered members cannot view attachments on my forum, while guests (logged-out visitors) and admins can view the same attachments without any problem.

When a registered member clicks an attachment, they see the message "you cannot access this attachment" instead of the file.

Details I've already checked:

• The affected file is a JPG (e.g. /wp-content/uploads/wpforo/default_attachments/[filename].jpg), so it's not an extension-blocklist issue.
• Under Usergroups → Registered → the permission "Front - Can access to attachments" is enabled (checked).
• The affected member is in the Registered usergroup only — no secondary usergroup assigned.
• It happens on every forum, not just one, so it's not a per-forum access override.
• Admin accounts can view the attachment fine; guests can also view it. Only registered members are blocked.
• In the browser Network tab, all requests return HTTP 200 — there is no 403 or 404, which suggests the "cannot access" message is being generated by wpForo's own permission check rather than blocked at the server level.

Since the "Can access to attachments" permission is enabled but registered members are still denied, this looks like it may be a bug or a permission/cache issue on wpForo's side rather than a misconfiguration.

Could you advise:

1. Is this a known issue in the current wpForo version?
2. Is there a permission cache I should rebuild, or a setting I may have missed?
3. What wpForo and add-on versions are affected, in case I need to update?

I am using wpforo 3.1.2. I know there is an update but not sure if that will solve the issue.

Thanks for your help.
