Can't see blog entry

Hi,

I’m trying to include a blog page following the manuel on your site (http://skywarriorthemes.com/instructions/oblivion/) but nothing works.
The Blog Settings parameters is well filled with the id of my blog category (3).
I’ve created a page with the “Blog full width” template.
Nothing appears on my website.

I have noticed that I had to manually create the blog category. Is it normal ?

Thanks for your help
Mikaël
