Overview[edit]
References are shown by adding the <references /> tag or the {{reflist}} template.
Issues and resolution[edit]
Parameters such as style or id were passed to the <references /> tag.
Only the group parameter is allowed. Using the {{reflist}} template will avoid most of the possible issues with the <references /> tag. See the documentation for details.
Since the addition of reference groups, this error should no longer be invoked— the message MediaWiki:Cite error references invalid parameters group will be displayed. If you encounter this error, please report it on the talk page.
