Question Dosnt like Community Builder

Ok, just upgraded from Joomla 1.5.7 to 1.5.14.
Installed Kuena 1.5.5 then had an issue where I changed the profile settings to community builder and hit save. Then when I went to return to the Kuena Component in the Components list the paged went to a white server error screen.

After this and reading some threads here, I downgraded to Kunena 1.5.4.
The following pic describes the information recieved on Downgrade:



I still was recieving the white page after this up/downgrade...
Until this morning when I happened to figure out the MySQL and found where to make the changes to the back end of the Kunena Configuration jos_fb_config

Now, it works after changing the:
Avatar intergration back to Kunena
Profile Settings back to Kunena

I was recieveing these warnings after I got it back up,



I reverted back to 1.5.5 and all seems to be working so long as I do not change to community builder settings...

Why isnt this pic working?

So whats the fix? How do I make it work with Community Builder?

Kunena should detect possible errors in CB settings and report from them. It seems that I may have missed one of those problems..

Can you look at your Apache error log when you get that error? You should get fatal error. Please report it back to me, so I can fix this problem.
