Guests can't see forum

[Sunsi]

Hello, I have a forum on my forum that I want everybody to see, so also guests, non registered persons et cetera. I have been trying to figure out how to do that, but when I log out myself, everytime I see the notice that I am not registered and that I should register before I am able to see anything of the forum.
In 'Forums & Moderators' - 'View permissions' when I click on the forum I want everybody being able to see, and then click on 'change (COPPA) Users Awaiting Moderation', I go to another screen and it says:
Can View Forum
Yes

Can View Thread Content
Yes

Can View Others' Threads
Yes

So I don't get it why people still can't see it.
