Hello. I installed Kunena 5.0.3 on my Joomla 3.6.4 and don't have CB anymore, because I like the Kunena profiles much more. I installed uddeim some months ago and still have the problem that there are many 404 errors. This happens when I click on the user name in a PM and also when I click on "Forum", because the link "shows index.php/component/kunena/", not "index.php/kunena" as it should be.

Will there be a change soon?

Hello, i've the same probelm: when I click on the user name in a PM the link show:

/forum/userid-3341.html?func=profile

and not:

/forum/profilo/3563-alex1981.html

How can i solve?

I also had this as well, but I found the solution for this one.
Under the Integration tab-> Show menu entry= Kunena 3.0+
Under the Integration tab-> Show thumbnails= Kunena 3.0+

I hope that helps.
