This is a tracking category for CS1 citations that have |edition= errors.
|<param>= has extra text
The templates are responsible for static text rendered in the citation. When |page=/|p=, |pages=/|pp=, |quote-page= or |quote-pages= is used in a template, cs1|2 inserts the appropriate pagination prefix 'p.' or 'pp.' ahead of the value in the parameter so:
|page=123renders as:
and:
|page=123–125renders as:
The templates emit this error message when various forms of p, pp, pg, pgs, page, or pages are found in the value assigned to |page=/|p=, |pages=/|pp=, |quote-page= or |quote-pages=.
To resolve this error, remove the extraneous text from the parameter value.
Pages with this error are automatically placed in Category:CS1 errors: extra text: pages.
