A question

[trialnick]

Hi there!

I use mybb1.6 , theme Apart.
I installed Google Seo and it works very well. I want to ask a question :

When I go to my site and type:

Code:

http://www.mysite.com/usercp.php?action=checkthis

---

(this is intentionally written)

or

Code:

http://www.mysite.com/misc.php?action=checkthis

---

I don't get 404 page error but blank page with 0.

Can't google seo make these blank pages as error 404?

thanks
