Figured it Out. What happened is that when I downloaded the Kunena Forum, it was an older version as the Joomla.org site wasn't updated with the 'newest' 5-21 one or something... I must've just had the older one just before that date. I know it had to be my own messup somewhere. Here's how I installed everything this time, a 100% completely fresh and new install to the server.

Now I just need to find someone who can create me some really good World of Warcraft-like graphics for our Guild site using that Dimenions Template I purchased, because it has the perfect 'layout' I enjoy and a nice time-of-day appearance adjusting template.

OK, just a comment. First of all: kudos to the Joomlapolis team for creating CB 1.2 - amazing add-on!

Now, I too tried to get Kunena working with CB 1.2.0 and 1.2.1 but to no avail...until I found this thread. My mistake? I installed Kunena 1.5.0, the native version for Joomla 1.5.10 which is what I'm using. Uninstalled 1.5.0 and installed 1.0.10 and hey presto, it works. But why do I have to run the Joomla 1.0.x version of Kunena in legacy mode to get it to work in the first place...?

First, the annoucement was quite clear that the Integration was for CB 1.2.1 Kunena 1.0.10 only. Second, the Kunena team is supporting two branches, one for J1.0.x and the other for J1.5 so they need to make each functional change to both branches. They have not released the 1.5 version with the new changes yet. I understand there is an SVN verstion that may be available for testing. The stable release (or an RC?) for J1.5 native that supports these new features will be availble when they have time.

OK, just want to emphasize - not trying to place blame on anyone here. I understand that people create this in their spare time etc. I was just curious as to why this was, and well, there's the reason. Thanks!
