Kunena Editing Error: "404 View not found [name, type, prefix]: topic, html, site"

[tp_finish]

I recently upgraded to Joomla 4 (4.3.2) and I am not able to use any of the buttons on a message such as Edit, Reply, etc. in my Kunena Forum; when I try, I get a 404 error that says "404 View not found [name, type, prefix]: topic, html, site"

I have tried a few remedies that I found online, and none have worked.

Here is an example of the issue:

1. This is a message posted: https://finishingandcoating.com/index.p ... s-engineer

2. When I go to "edit" it, the link is "https://finishingandcoating.com/index.p ... r/edit/107" which sends me to the "404 View not found [name, type, prefix]: topic, html, site"

It happens whenever I want to edit or reply to a message.

Any suggestions would be much appreciated, and thank you.

Perhaps an alternative question for this might be: would it be possible to extract all of the postings etc from my current Kunena installment in my php tables and save it; then delete and reinstall fresh a new Kunena, then upload the old php tables and have it run?

Have you tried updating Joomla and Kunena to the latest versions? The latest versions are Joomla 4.3.4 and Kunena 6.1.3.2.

Load the Webdeveloper tools (F12) and go to the Console tab. Two errors are highlighted:

Failed to load resource: the server responded with a status of 404 () https://finishingandcoating.com/templat ... system.css

The folder templates/system/css belongs to Joomla 3.x. Either the paid JA Focus template or the T3 Framework tries to load this file. The T3 Framework was developed to be compatible with Joomla 3.x, but version 3.1.3 seems to work with Joomla 4, too.

76-hohman-plating-process-engineer:1 Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received

Just a guess, but is the server perhaps blocking some requests through the Apache module ModSecurity, configured by the host?
