Well I just tried phpNuke version 6.5Beta8 with KISGB and forget about it. FB has done all kinds of changing tables and field names to integrate phpbb into phpNuke. Personally I think it's a bad move. Modules and Blocks may be breaking all over the place because of this. DO NOT TRY TO USE THE CURRENT PHPNUKE VERSION OF KISGB WITH VERSION 6.5!!! I personally take issue with FB's methodology to make such drastic changes in the name of integrating a forum application. phpNuke is supposed to be a Portal/CMS. It's purpose is to provide the framework for applications, not to be an all-in-all in and of itself. I have a preliminary fix working for KISGB. You can test KISGB with phpNuke version 6.5 here. By version 6 of any software application you should not be making these types of changes, imo, unless you also provide a seamless integration. If you want to test KISGB with phpNuke 6.5x, contact me for the fix until I publish it.
