I have duplicated the blog, following the documentation and got everything looks like up and running. Got all the web controls and pages stored in a separated folder. All tables and stored procedures were created. When I post a blog, it works fine. I can edit it. However, I cannot view the post, by clicking on the title. It returned with blank page. 

I have trace it down and for some reason, when the viewpost.aspx always has ItemID = 0. I have tested it with the all parameters tested with calling the viewpost.aspx page directly (instead of using the vitual path "~\test.aspx"), it works great.

It will be greatly helpful if anyone point me to a direction which I can figure out why the item ID is not being populated.

Thanks in advance.
