Help:Cite errors/Cite error references invalid parameters

Overview
References are shown by adding the tag or the reflist template.

Issues and resolution
Parameters such as  or   were passed to the  tag. Only the group parameter is allowed. Using the template will avoid most of the possible issues with the  tag. See the documentation for details.

Since the addition of reference groups, this error should no longer be invoked— the message will be displayed. If you encounter this error, please report it on the talk page.
