Problem with showing posts from all blogs to main blog

Hi,

I have a problem with showing posts from all blogs in my multisite to main blog.

I use plugin http://wordpress.org/extend/plugins/wordpress-mu-sitewide-tags/ .

I dont know where can be problem. When someone create a post, the post copy to main blog, but when I click to post I get error “Not found – Sorry, but you are looking for something that isn’t here.” also comments are blocked.

Someone know where can be problem?

Thanks

btw: sorry for my english :-/
