I want to try the nForum features so I can install the Forum module on top of my Umbraco.

* I have created a test site with standard Umbraco installation and installed the MVC starter kit.

* Installed the nForum v1.7

Everything went smooth...until I created a test category and accessing it.. then it gives error..

My test site is up and running here:
http://umbraco.oviyaitsolutions.com.tropaeolum.arvixe.com/

Forum:
http://umbraco.oviyaitsolutions.com.tropaeolum.arvixe.com/forum.aspx

I have created a test category in the backend... but as you can see.. the forum page still says it doesnt have any categories.

But I have created the category and link to it:
http://umbraco.oviyaitsolutions.com.tropaeolum.arvixe.com/category1.aspx ; (Throws an ERROR)

nForum - Configurations:
http://umbraco.oviyaitsolutions.com.tropaeolum.arvixe.com/about.aspx

What am I doing wrong since it throws me error on category page?

Please advice me for further progress...
