All {{cs1}} and {{cs2}} templates report this error when one of the [[URL]]-containing parameters cannot be paired with an associated title. This error may also occur when {{para|title}} cannot be linked with {{para|url}} because the citation also contains a conflicting {{para|title-link}} parameter.

A unique case exists for {{tl|cite journal}}: if {{para|pmc}} or {{para|doi}} has a value, {{para|url}} is omitted or empty, and {{para|title-link}} does not point to an article, then {{para|title}} is automatically linked with the same URL as the PMC or DOI. This default behaviour can be overridden using {{para|title-link|none/pmc/doi}}.

Because URLs are ugly and generally uninformative, it is expected that editors should provide a meaningful title for each URL. In most cases this can be accomplished by using the {{para|title}} parameter.

To resolve this error, provide an appropriate title for the URL-containing parameter. In the case where {{para|url}} and {{para|title-link}} are contending for {{para|title}} you must choose which one to keep. Consider moving {{para|url}} or {{para|title-link}} to a more suitable parameter.
