External links in a rendered citation are a combination of url-holding parameters, {{para|url}}, {{para|chapter-url}}, etc., with title-holding parameters, {{para|title}}, {{para|chapter}}, etc. Title-holding parameters may be [[wikilink]]ed to another Wikipedia article but not when there is a matching url-holding parameter in the citation. When this condition occurs, the wikilink is suppressed, the wiki markup ignored, and the rendered citation links to the external site.

Some [[Help:Template|templates]] will also cause this error if they are part of a title-holding parameter. The error occurs when the template produces wikilinked content. For example, {{tlx|lang}} templates output a wikilinked category. Templates in url-holding parameters may also corrupt the citation's [[WP:COinS|COinS]] metadata. As a general rule, avoid using templates in title-holding parameters unless you know that the template's effects are entirely visual ({{tlx|!}} and the like).

This type of error may also occur in identifier-based templates ({{tlx|cite doi}}, etc.). When this happens, the error message is shown in the article but the error is actually located in the identifier-based citation template.

To resolve this error, remove wikilinks from title-holding parameters that are intended to be externally linked or remove the external URL, which will allow the internal wikilinks to work as expected. If wikilink-producing templates are important to the citation, move them out of the CS1 template but leave them inside the citation's {{tag|ref}} tags. Some of the functionality provided by templates may also be available through CS1 parameters.

To resolve errors in identifier-based citation templates, the template must be edited to correct the error. Exercise caution when editing these templates because identifier-based citation templates are often used in multiple articles.
