Have you installed the Community Builder? Unzip my uploaded file and replace with this file the KunenaForum.php. Path is libraries/kunena/src/Forum/KunenaForum.php

Yes, CB is installed, version 2.8.0
Your file unzipped and uploaded, unfortunately nothing has changed

==update==
actually, something has changed:

Please do not drag images into the editor text field, use the "Add Files" option.

actually, something has changed:

Works now?

Please do not drag images into the editor text field, use the "Add Files" option.

Oh, sorry! I don't see the "Add files" option in the editor, 'm missing something, please apologize.
To load images I'm requested to use the URL notation, hope it works.

Works now? 

No, the only thing changed is a red warning on the site control panel which says "Please complete Kunena installation!" (the image I'm trying to attach is a screenshot of that).

Sorry, I don't know how to attach images.
Plus, a piece of text is not accepted, why?!?!?!?
The sentence in the previous post was: "I do not see the "Add files" option in the editor, though; probably I am missing something, please apologize."

No, the only thing changed is a red warning on the site control panel which says "Please complete Kunena installation!"

What happens when you go to the Kunena dashboard?
.

The sentence in the previous post was: "I do not see the "Add files" option in the editor, though; probably I am missing something, please apologize."

You don't have these options?
.
 

What happens when you go to the Kunena dashboard?

Nothing; but I guess is better to solve the attachments issue I have, otherwise is nearly impossible to explain myself clearly.

You don't have these options?

No, I don't. I see only the editor section, not the Attachments one.

No, I don't. I see only the editor section, not the Attachments one.

The button "Add Files..." is definitely available here. If you don't see it, try another browser.

On my laptop (Fedora 36) I'm using Firefox, I tried with Brave, and even with Edge on a Windows 11 virtual machine: no way.
Could it be that I'm not allowed to attach anything since I'm a newbie? I've seen that in other forums
