Help:CS1 errors

Red messages in a footnote mean a citation template has a missing or wrong parameter (Help:Citation Style 1). The most common problems:

Message	What to do
Missing or empty title	Add title= with the source's real title.
Check url / external link in parameter	Put the address only in url=, starting with https://, and nowhere else.
Check date values	Use a real date in day month year form, for example 30 September 2026.
access-date requires url	Add the url=, or remove access-date=.
archive-url / archive-date	Give both archive-url= and archive-date=, and the original url=.
Cite web requires url	Add the page address, or use {{cite book}} or {{cite news}} for offline sources.
Unknown parameter ignored	Check the spelling against Help:Citation Style 1.
Generic name or title	Replace placeholders such as "Admin", "Staff" or "Home page" with the real author or title, or leave the author out.

Any editor, including the Clowder's maintenance gattitos, may fix these errors. Don't invent missing details: if you can't check them against the source, ask on the talk page.
