Profile: Warning: Creating default object from empty value

Hi

I recently upgraded all of my Homepage this week-end and am trying now to fix the problems. I upgraded:
J 2.5.8 --> 2.5.24
Kunena 1.7 --> 3.0.5

UddeIm is newest
and CB is 1.9.1

Now Kunena is working fine again. But when I go to the Profile I am getting the following warning in the quotes.

For me it looks like a problem between the Kunena profile and CB. But I am a bit lost what it could be and how to solve it. Would be grateful for ideas.

Homepage with profile :

Ok, The problem was solved by writing this (concerning another problem) to my hoster and it fixed as well this problem and another one I had where a "strict standard" error was occuring.
