Category:Navseasoncats using unknown parameter

This is a tracking category.

It is used to build and maintain a list or lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the encyclopedia's categorization scheme.

More information:

• This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
• These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
• These categories also serve to aggregate members of several lists or subcategories into a larger, more efficient list (discriminated by classifications).
• Typically, tracking categories are automatically populated by templates invoked in pages or by the MediaWiki software (see Special:TrackingCategories for an overview of the latter).

Administrators: Please do not delete this category even if it is empty!
This category may be empty occasionally or even most of the time.

This maintenance category contains pages where {{Navseasoncats}} or Module:Navseasoncats uses an unknown parameter. This could be either:

• an unnamed parameter such as {{Navseasoncats|example}}, or {{Navseasoncats| }}, or
• a named unknown parameter such as {{Navseasoncats|catt = example}}, or {{Navseasoncats|decade = example}}.

To correct the problem, investigate the template hierarchy and remove {{Navseasoncats}} or Module:Navseasoncats' use of the unnamed/unknown parameter, being aware that the parameter might be necessary elsewhere.

Pages in this category should only be added by Template:Navseasoncats and Module:Navseasoncats.
