WordPress MU

Hello,

I have a "strange" problem. When permalinks are set to default, all works, but setting anything different that, categories, posts and all elements work fine. Pages not! I cant reach pages; clicking them always open homepage. Example: mysite.com/blog/category/section-one works fine; mysite.com/blog/section-one/post-one too, but mysite.com/page-one not, it redirects to homepage.
Sub blogs are working fine, even when set permalinks to custom structure like /%category%/%postname%/

I have reviewed all configs and data, but I couldnt find antyhing wrong.
Anybody have dealed with same problem? How to solve it? I think thats a little, little problem, that I cant see.
Cheers!

Note how it stuffs the /blog/ term in the permalinks.

So , yourdomain.com/pagename/ won't work.

yourdoamin.com/blog/pagename/ should.

So , yourdomain.com/pagename/ won't work.

yourdoamin.com/blog/pagename/ should.

@andrea_r, it doesnt work too, I've already tried.

In old test server all links work fine, without /blog/.
Btw, in pages edit, I cant set permalinks with slashes, inserting /blog/ before post id. So, I always receive mydomain.com/page-name.

I think that root of problem is rewrite. I found another post with same problem, but there is not solution for it.
Thank you!

If someone can reproduce the problem, then we might be able to help.

And by reproduce, I mean using the same version, on a different host, in a subfolder install, and getting the same results.
