Category:Wikipedia message box parameter needs fixing

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 as empty!

This category may be empty occasionally or even most of the time.

This is a Wikipedia maintenance category.

This category is automatically populated by the templates {{ambox}}, {{tmbox}}, {{imbox}}, {{cmbox}}, {{ombox}}, {{fmbox}} and {{dmbox}} and by other message boxes that use those mboxes. Pages that feed the wrong parameters to the mboxes are put in this category. This is so we can easily find those pages and fix them.

The most common fix that needs to be done is:

• {{ambox|type=anything}} – The mboxes detect and report cases of any invalid value, such as "type=fun". Change to one of the valid values, for instance "type=notice".
• {{ambox|image=blank}} – The "image=blank" option is now deprecated. It currently falls back to "image=none" so nothing breaks, but all usage of "image=blank" should be changed to "image=none".

Subcategories that get listed here are not subcategories in the normal sense. Instead they happen to use a message box in the wrong way and thus need fixing too.

If some case is too tricky or a page is protected so you can't edit it, don't worry. More experienced editors and admins will work through the cases that get left in this category.

MediaWiki runs updates of category listings (as the one you see below) as a low priority job. Thus if the servers are very busy it can take some hours before a page is removed from the list below, even though the page has been fixed. But normally it is removed within some minutes.

Sometimes you need to purge a page to see your change of a message box and to get rid of this category from the bottom of a page.
