I have used "auto-login hacked" regularly But I have a problem

After I installed "auto-login hacked", in order to check it I clicked "Logout". And though "You are now logged out Thank you for your visit to our site!" was displayed on a screen, I could not logout. Because "User Menu" was displayed on a screen
On the following day though I checked it, "User Menu" was still displayed on a screen I clicked "Logout", but "Now and logging in automatically" was displayed on a screen and I cannot logout.

What should I do?
