This category contains pages transcluding a template with unknown parameters (undefined, misspelled, etc.).
Pages are typically sorted alphabetically by the unknown parameter that is used, e.g. pages using unknown parameter |foo= will be sorted under "F". The name of the page is typically used as a secondary sort key.
Unknown parameters can be detected using Module:Check for unknown parameters in the template. To show the information listed here on a category page, use {{Unknown parameters category}} on the category page.
This category contains subcategories listing articles that transclude templates where unsupported parameters are used. See the subcategory pages for the specific template parameters that need to be updated.
This category currently contains no pages or media.
