Much better than post a URL to my UBB is that I found the so said BUG,
it's not really a code bug, but a logical error. It has to do with the Reistrations Settings. I will quote some words from the CP Reg Settings:
"Display Registration Option Wording?:
Always leave this option set to Yes unless none of your forums require registration. If you do not plan to use registration options anywhere, you may set this to NO. Removing registration wording means that the registration link will NOT be displayed anywhere on your site!"
Infopop you said that the !Reg Wording! wont be shown! But the LogOut wording will be removed also.
It's better to say that or unlink the LogOut Wordings from that setting.
