This category contains pages transcluding Template:Infobox person (talk) 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.

Note: Unlike most "unknown parameter" categories, this category tracks usage of empty unknown parameters as well as those with values. See the template talk page thread from December 2022 for more information.
