Permalinks not working

When you saved the setting to “post name”, what message do you get,

is it,

You should update your .htaccess now.

or

Permalink Structure Updated

You should update your web.config now.

That’s what it says, I actually had not noticed it said that, thank you. How do I update that?

See https://codex.www.ads-software.com/Using_Permalinks

Particularly from “Using “Pretty” permalinks” down.

thank you
