@eviltrout is there a site setting to enable this? I don’t think it’s enabled here on meta.
It’s available whenever personal messages are enabled so it is here on meta, if you visit your preferences → users page.
As for the bug in the initial post, I can’t seem to reproduce it. Are you hitting “Save Changes”? If I do so and refresh the page it is still disabled.
Unless you can reproduce it here, it’s a bug with your local instance of some kind.
