Category:Pages with templates in the wrong namespace

General
There are templates that should only be used in one namespace or a limited number of namespaces. If those templates are used in other namespaces, then they will likely populate this category. Many templates use the "demo" or "nocat" parameters to allow usage in other namespaces.

Specific
Some redirect category (rcat) templates may only be used in one or two namespaces, while others may be used in any namespace. Still others can be used in all but one namespace. An rcat's template documentation is required to show if there are any namespace limitations.

If an rcat template is used to tag a redirect that is in the wrong namespace for that rcat, or if any template is used in the wrong namespace, then instead of populating the appropriate category, it may populate this category. Be sure to have your User Preferences – Advanced options  set to "Show hidden categories". Most rcats place redirects into hidden categories, like this one, and you will not be able to see the hidden categories on redirect pages until you set your preferences to "show" them.

The four pages that should appear in this category are:
 * Template:Incorrect namespace
 * Template:Incorrect redirect template
 * WikiDevi:Template messages/Redirect pages
