Problem with the blog

Hello.
I have a problem to set up the blog on my website.
I created a page named Blog. Then in Appearance/Custumize/Static Front page I chose Blog for article page. But nothing happens. When I go back to the blog page there is no access to dashboard and I only can see the header.
Can you help me ?

Please give us link to your website and be sure you choose page’s template as blog or default.
