UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 5 Support Page Links in Topic View

I suspect this question will take only an instant to answer, as I'm convinced this is a basic UBB feature for which I just can't find the Control Panel toggle for, but:

How do you enable the multi-page topic page links in the forum/topic view in UBB? That is:

Topic Name
Page: 1 2 3 4 5

It's a feature I see on many other boards, including this one, but I can't find where it's set. I'm "back" at version 5.4.4 - is it something that was added later?

Thanks.
