The Kunena team has announce the arrival of Kunena 7.0.4 [K 7.0.4] in stable which is now available for download as a native Joomla extension for J! 5.4.x/6.0.x. This version addresses most of the issues that were discovered in K 6.2 / K 6.3 / K 6.4 and issues discovered during the last development stages of K 7.0
Yesterday I attempted to upgrade Kunena to 1.6 and crashed the front end of my site. Everything was a blank page!
The backend worked except for kunena... If I clicked the kunena component it would also go blank... I had to do a full restore so I didn't get a change to generate the error logs from the backend like you like... I did however turn on error reporting in joomla and got the following back:

It looks like you had old 3rd party modules/plugins from Kunena 1.5 installed. They do not check Kunena version. They just try to use functions -- and fail because of most of the code has been changed in Kunena 1.6.
So it was not Kunena that caused this -- you get the same error by uninstalling Kunena 1.5.
You need to remove all old modules and plugins that you have installed for Kunena 1.0/1.5 before installing Kunena itself. That includes CB forum plugin if your CB version is <1.2.3 (CB plugin issue has been fixed later).
