Berlin Theme=>hide fields

How do I hide/supress fields in the public side?

I see:

but this does not seem relevant.

You’ll click on settings and then click themes. Then on your current theme there usually is a “Configure” button, which will allow you to choose which dublin core fields to display on the public site.

Have you tried the HideElements plugin ?
