Post doesn't hide from my website

Hi,

I have just installed the plugin and even though I have the settings as instructed https://screencast.com/t/RWVQ7vQ10y I can still see my blog post together with all other blog posts on my website.

I need it not to be visible on my website anywhere, but only accessible via a URL. I don’t wish to make it into a page as I have another pluggin Digg Digg to have social media floating icons.

Am I missing something?

Thanks,
John
