help. installed theme, doesn’t come with pagination function? <!–newpage–>

hello. i’ve installed a theme and for some reason it’s not showing the “PAGE: 1 2 3 4 5” part.

i’ve included <!–newpage–> into some articles because they were a bit too long. If I switch to the default theme, I can see the “PAGE: 1 2 3 4 5”. but when I go back to this custome theme, it doesn’t show it. does anyone know the code from the default theme to make this show up?

i’m new, sorry.
