I am having problem of "Object reference not set to an instance of an object" when I am implementing YAF using steps given on your website by maing "forum" folder in our existing website.

This is a bug in that Version. If you know how to compile yaf yourself you could grab the latest source code from the CodePlex Repository and compile the fixed version yourself.

Or you download the YAF.SampleWebApplication - C# Version  from the Documentation Page 

And extract the updated dlls (excluding the YAF.SampleWebApplication.dll which you don't need) from that Version (it the 1.9.6.2 Version including this fix for the bug above).

Hi, tha_watcha

Thanks for the reply.

I have downloaded the sample webapplication prepared by you but still in that also I am getting same error in that application while integrating master page.

How should I implement it, is there any other way?

Thanks in advance.
