Question Call to undefined method JController::getInstance() in \...\components\com_users\users..php

That didn't solve my problem

Can we see your updated and unedited K 1.6 configuration report, please?

Third-party components: UddeIm 2.2

Third-party SEF components: None

Plugins: System - Mootools Upgrade: Enabled | System - Mootools12: Disabled

Modules: Kunena Latest 1.6.2

You did not change your configuration settings. Please set your Kunena config. settings back to their original default values and test.

You did not upgrade Kunena Latest module.

(You didn't change SEO, either, but that's not that important)

I don't know why Kunena Latest is still here, I don't have it in modules.

Restore Default Settings - I already did that!

I don't know either. Why don't you upgrade to Kunena Latest 1.6.4?

I think your website may be corrupted. Unfortunately, because it's an intranet site, we can't get to it to diagnose it from this end.

How many messages are posted on your forum? Maybe you could consider uninstalling Kunena ... possibly drop all jos_kunena_* tables, too, and re-install?

How did you install Kunena? Did you use the Joomla Extension Manager to install or did you just FTP the files onto the server? Did you read K 1.6 Installation Guide ? I don't know how to help you except for asking you a lot of questions that start with "did you check this".

Your configuration report also shows that your Kunena menu is messed up.

Have you ever had K 1.6.x working on your site?
