Overview

edit

References may be defined within the reference list:

{{reflist|refs=
<ref name=rename1>refcontent1</ref>
<ref name=rename2>refcontent2</ref>
}}

List-defined references may be within groups:

{{reflist|refs=
<ref name=rename1>refcontent1</ref>
<ref name=rename2 groupname=groupname>refcontent2</ref>
}}

Issues and resolution

edit

A list-defined reference uses a group name that is not used within any <ref>...</ref> tags. All list-defined references must be used or commented out.

The message also appears if you mistakenly embed {{sfn}} or {{sfnp}} (rather than {{harv}}, {{harvnb}}, or {{harvp}}) inside <ref></ref>:

<ref>{{sfnp|Foo|1999}}</ref>

This message does not show in preview mode.
