Category:CS1 errors: deprecated parameters

This category tracks pages using citation templates that use deprecated parameters.

CS1 templates add pages to this category when the citation contains any of the deprecated parameters listed in the table below:

Deprecated CS1/CS2 parameters
Deprecated parameter Replace with Date
|booktitle= |book-title= April 2021
|chapterurl= |chapter-url= April 2021
|episodelink= |episode-link= April 2021
|mailinglist= |mailing-list= April 2021
|mapurl= |map-url= April 2021
|nopp= |no-pp= April 2021
|publicationdate= |publication-date= April 2021
|publicationplace= |publication-place= April 2021
|serieslink= |series-link= April 2021
|transcripturl= |transcript-url= April 2021

By default, Citation Style 1 and Citation Style 2 error messages are visible to all readers and maintenance category messages are hidden from all readers.

To display maintenance messages, include the following text in your common CSS page or your specific skin's CSS page (common.css and skin.css respectively):

.mw-parser-output span.cs1-maint {display: inline;} /* display Citation Style 1 maintenance messages */

To display hidden-by-default error messages:

.mw-parser-output span.cs1-hidden-error {display: inline;} /* display hidden Citation Style 1 error messages */

Even with this CSS installed, older pages in Wikipedia's cache may not have been updated to show these error messages even though the page is listed in one of the tracking categories. A null edit will resolve that issue.

To hide normally-displayed error messages:

.mw-parser-output span.cs1-visible-error {display: none;} /* hide Citation Style 1 error messages */

You can personalize the display of these messages (such as changing the color), but you will need to ask someone who knows CSS or at the technical village pump if you do not understand how.
