Question J! 1.7 + K 1.6.4: Installed, set up, . . . nothing.

I have the exact same problem. Installed 1.6.4 on a clean install of Joomla 1.7 RC1 and I get the same error message like the second message. I have tried replacing that file, but it doesn't help.

With this file it should help for the issue like described above, /administrator/components/com_kunena/libraries/integration/joomla16/access.php :

Nope. No go. This time I get this:

Fatal Error was detected!

Fatal Error: Declaration of KunenaAccessJoomla16::loadAllowedCategories() must be compatible with that of KunenaAccess::loadAllowedCategories() in components/com_kunena/libraries/integration/joomla16/access.php on line 261

Oh, and on the backend, the Forum Configuration doesn't work properly either. All I get is a blank page with some links at the top.

This one should be the right :

Sorry, but no. This time I get this:

Fatal Error: Cannot make static method JFile::copy() non static in class CKunenaFile in components/com_kunena/lib/kunena.file.class.1.5.php on line 156

The error was detected in the Kunena Component.

On the upside, the forum configuration in the backend works now.
