Doesn’t ask for login or registration

Hi,
Even I am not log as a user when I ask to access a protected page the system consider that I am a user already connected, I dont get the login and register page.
On the wp-members parameters the corresponding page is cited as a login page.
Please could you access my website and have a look on this page
Thank you to tell me your access result: do you get the page indicating “Merci pour votre inscription” or are you asked for login or registration.
Thank you.
