Hello Support Team,

I recently purchased the User Mentioning addon.

My environment:

  • wpForo 2.4.5

  • User Mentioning 3.3.4

  • Ultimate Member integration (UM 2.10.4, multiple UM Pro extensions installed)

  • PHP 8.2 / MySQL 5.7

  • Better Messages / Formidable Forms also installed

I have already done the following:

  • Enabled Usergroup access permission for all roles

  • Synced user profiles several times via wpForo Maintenance

  • Rebuilt caches, flushed permalinks (both hard and soft)

  • Checked wpForo > User Mentioning settings (By Default Suggestion is ON for Topic Participants)

The problem:

  • @mention suggestions only show site admin account

  • Other registered users do not appear in the suggestion list even when typing a few characters

  • Existing topics with participants also don't suggest them after typing @

My assumption is that maybe the Ultimate Member profile fields (display_name) are not linked properly for wpForo mentioning system.

Is this caused by limitations of standalone addon?

If so, I am considering upgrading to the full wpForo Bundle — please advise whether it is recommended, or if there is any other solution to fix this problem in current license.

Thank you very much for your help!

Hello,
Thank you for your help. I would like to provide additional details about the issue:

Environment:

  • wpForo Version: 2.4.5

  • wpForo User Mentioning Addon Version: 3.3.4

  • PHP: 8.2.20

  • MySQL: 5.7.36-log

  • Web Server: Apache

  • WordPress Theme: 2022

Issue Summary:

  • The mention suggestions only display the administrator user.

  • Other users do not appear in the suggestions, even after typing @ followed by several characters (including Japanese characters and alphabet).

  • Previously, one user appeared in the suggestion list, but now no non-admin users appear at all.

  • New users also fail to appear in the mention suggestions.

What we have tried:

  • Checked and adjusted User Mentioning addon settings (suggestion limits, delays, topic participants, following users, etc).

  • Confirmed that user roles and forum access permissions are correctly set.

  • Ran full wpForo maintenance: user profile sync, user cache delete, forum cache delete, forum statistics update, thread rebuild, etc.

  • Verified that wpforo_profiles table correctly includes all users.

  • Re-registered users to ensure profiles were properly created.

  • Even after these actions, the issue persists.

We would appreciate your advice and suggestions to resolve this problem.
Thank you very much!

This is a server configuration issue. The admin-ajax.php file is being blocked on the server side. Please contact your hosting provider and ask them to check the server settings.

Thank you for your previous support.

We performed the debug test as you advised.
We directly called

error_log(json_encode(Better_Messages()->functions->get_chat_participants($thread_id)));
 

And the result was

0

Currently, the get_chat_participants() function returns 0 even when the chat thread has participants.

Environment:

  • wpForo (v.2.4.5)

  • wpForo Advanced Attachments (v.3.2.3)

  • wpForo User Mentioning (v.3.3.4)

  • Better Messages - WebSocket Version (v.2.8.9)

If you need any additional information to investigate, we would be happy to provide it.

Thank you very much!

We don’t fully understand your last post.

When you call /wp-admin/admin-ajax.php, it should always return 0 — this indicates that it's working correctly.

Please let us know if you’ve identified how /wp-admin/admin-ajax.php is being blocked.
Is it blocked via the .htaccess file, or possibly by another plugin?

Thank you again for your previous response.

We would like to provide further details regarding the @mention suggestion issue, and clarify some of our recent tests.

◆ Current Behavior

  • When using the "Reply" button directly under a post, the post author’s name is automatically inserted after @.

  • However, in the bottom "Reply" area (global reply field), only the admin user is ever suggested — even when multiple users have participated in the topic.

  • In topics without any admin participation, typing @ returns no suggestion at all, even if there are other participants.

This applies regardless of user role.

◆ Our Environment & Setup

  • We are using custom user roles (teacher_user, school_user, etc.) via a user role editor plugin.

  • All roles are properly assigned to wpForo usergroups and have forum access permissions enabled (e.g., “can reply,” “can edit own reply,” etc.).

  • Better Messages plugin was installed, but for this test, we have completely disabled it to avoid conflicts. The issue persists without it.

  • We have also cleared all caches, rebuilt usergroup mappings, and confirmed admin-ajax.php returns 0 (no block).

◆ Our Question

Is this limitation expected behavior with the User Mentioning addon alone?

Or does the full wpForo Bundle (or any specific addon) provide extended control over which users are suggested when typing @?

We’re happy to upgrade if needed, but would like to clarify this point first.

Thank you for your help!

Best regards,

@leena_a 

The developers have checked your website again. The admin-ajax.php file is returning a 403 Forbidden error.

It’s possible that our IP address is blocked, so we’re unable to fully test it. Please see the screenshot below.

In any case, if you’re not seeing the 403 error yourself, it might be because you're not entering any characters after typing @.
If you type only @, it will automatically display the participants of the current topic.

Try typing a character after @ and see if additional users appear in the list.

Our hosting provider has temporarily disabled the country IP restrictions on the server.
Please try accessing admin-ajax.php again to complete your tests.
The restriction will remain lifted for this week only (until June 28, JST).

In the meantime, we tested on our end again. Even after typing @ followed by a character, only the admin user appears in the suggestion list.

Just to confirm: should the User Mentioning addon suggest all topic participants—even non-admin users—after typing @ in the reply field?

Thank you again for your continued support.

Hi @leena_a,

This is a configuration issue. You’ve created a usergroup and assigned it to all members of your website, but this usergroup doesn’t have the necessary permissions — all “Can” options are disabled.

Additionally, the addon only allows mentioning users who have the “Display on Member List” option enabled.

Hello,

Thank you very much for your support regarding the mention issue.
After reviewing the usergroup settings based on your advice, we realized that the newly created “〇〇-2” usergroups didn’t have the necessary permissions enabled.

We apologize for the oversight on our end.
Once we corrected the settings, the mention feature started working perfectly. We truly appreciate your guidance and quick assistance!

Thank you again for your time and support.

Best regards,
