This error occurs for {{cs1}} and {{cs2}} templates when all of {{para|title}}, {{para|trans-title}}, and {{para|script-title}} are omitted or left blank.  At least one of these title parameters must be provided for each citation.

{{tlx|cite episode}} will show this error if {{para|series}} is omitted or left blank (even if a {{para|title}} is provided).

{{tlx|cite encyclopedia}} will show this error if {{para|encyclopedia}} has a value but {{para|entry}} (or another {{para|chapter}} alias) is omitted or left blank.

Sometimes this error occurs because an editor has used a CS1|2 citation as a [[Help:Shortened footnotes|shortened footnote]] when {{tlx|sfn}} or one of the {{tlx|harv}} family of templates would have been more appropriate. This error also occurs when an editor used {{tlx|citation}} but intended to use {{tlx|citation needed}}.

To resolve this error, provide a value for {{para|title}}, {{para|trans-title}}, and/or {{para|script-title}} or replace the CS1|2 template with a more appropriate template. If you are listing a periodical or an issue of a periodical in a bibliography rather than within {{tag|ref}} tags, {{tlx|List journal}} may be more appropriate.
