Show Or Hide Content shortcodes don't work

Hi,

I activated the Show Or Hide Content option and wrote in a page exactly the same text displayed in your informative site.

[uo_show for=’loggedin’]Content for logged in users[/uo_show]

[uo_show for=’loggedout’]Content for logged out users[/uo_show]

The page loaded when I was logged in, and I could see all content. The same behaviour occured when I was logged out.
The problem is that the two messages are always displayed doesn’t make difference if the user is logged in or logged out.
Why don’t the shortcodes hide the content?
May you please help me?
Thank you
