This error occurs when a {{cs1}} or {{cs2}} template includes more than one parameter that maps to the same meaning. For example, {{para|author}}, {{para|last}}, and {{para|last1}} are all synonyms of each other, so no more than one of these parameters should ever be used in a single template.

To resolve this error, remove or modify the redundant parameter(s).

*{{#invoke:Cs1 documentation support|help_text_error_messages|err_redundant_parameters|$1=editor-name-list parameters}}}}

This error occurs when a CS1 or CS2 template uses more than one type of author or editor name-list style.  There are three kinds of incompatible author-name-list styles: 
: {{para|author''n''}} and {{para|last''n''}} / {{para|first''n''}} (and their various aliases), {{para|vauthors}}, and {{para|authors}}
and similarly, three editor-name-list styles:
: {{para|editor''n''}} and {{para|editor-last''n''}} / {{para|editor-first''n''}} (and their various aliases) as well as {{para|veditors}}

To resolve this error, choose one name-list-style.  Use the chosen style for both of the author and editor name-lists.
