Hi all I am kind of new to the whole dnn thing. I was asked to take over a website for my community and I am having a problem setting up the forum module. Any Help would be greatly appreciated! I can and users can post to the forum, but myself or a user clicks on the new thread, you get the following error message:

A critical error has occurred. Object reference not set to an instance of an object.

 

The Forum version is:

Forum

The core forum module for DotNetNuke.
