You say the page exists. Doe that mean you can see it in your browser?
If Yes, Go to the page in the Browser and hit CTRL +, this will clear your cache memory. So many times when we make changes to a page they don’t show up because the browser doesn’t refresh the page.
Another option, was the page published at one time and since then you have changed it’s Status?
Yes – http://www.bluereek.com/bluereek-blog/page/2/ – I can see it in the browser (but not listed as a page).
I just re-read your question. There is a page for your blog but it is blank. The content for that page comes from the Post area. Check your posts to find whats on this page.
