I'm trying to register a couple of settings, but as soon as I try to set
one of them (in the admin interface) I get a "NoneType takes no

after that, aka nothing gets saved).
I'm assuming these are in your defaults.py?
Add default="" to the new settings, that might be the only trick required.
BTW, your TEMPLATE_ACCESSIBLE_SETTINGS call probably doesn't need
description or editable, as you've got the append=True so it'll
take those properties from the one defined before.
I've pasted some of my code below yours quoted below.
HTH. HAND.
Seeya. Danny.
Here's the code:
from django.utils.translation import ugettext_lazy as _
from mezzanine.conf import register_setting
register_setting(
name="TEMPLATE_ACCESSIBLE_SETTINGS",
description=_("Sequence of setting names available within
templates."),
editable=False,
default=("SOCIAL_LINK_FACEBOOK", "SOCIAL_LINK_INSTAGRAM"),
append=True,
)
register_setting(
name="SOCIAL_LINK_FACEBOOK",
label=_("Facebook link"),
description=_("If present a Facebook icon linking here will be
in the header."),
editable=True,
)
register_setting(
name="SOCIAL_LINK_INSTAGRAM",
label=_("Instagram link"),
description=_("If present a Instagram icon linking here will be
in the header."),
editable=True,
)
And here is the traceback:

My code is basically this:

from django.conf import settings
from django.utils.translation import ugettext_lazy as _
from mezzanine.conf import register_setting
register_setting(
name="SOCIAL_FACEBOOK",
description="Link to Facebook Page. Include http prefix.",
editable=True,
default="",
)
register_setting(
name="SOCIAL_TWITTER",
description="Link to Twitter Feed. Include http prefix.",
editable=True,
default="",
)
# ... and a few more ...
register_setting(
name="TEMPLATE_ACCESSIBLE_SETTINGS",
append=True,
default=("SOCIAL_FACEBOOK", "SOCIAL_TWITTER",
"SOCIAL_GOOGLEPLUS", "SOCIAL_YOUTUBE",
"SOCIAL_EMAIL",
),
)
