Details

The variable holds an array indicating which namespaces allow sub-pages. The array is indexed by the numeric namespace ID, and each array value is either 0 (no sub-pages) or 1 (sub-pages allowed). A categoryspace (namespace 14) subpage will work like any other category.

See Help:Subpages .

Enabling for a namespace

See also Manual:Namespace constants for a list of the NS_... codes.

The normal way to enable subpages for a given namespace is to edit the LocalSettings.php and insert the following:

# <translate nowrap><!--T:12--> Enable subpages in the main namespace</translate>
$wgNamespacesWithSubpages[NS_MAIN] = true;

# <translate nowrap><!--T:13--> Enable subpages in the template namespace</translate>
$wgNamespacesWithSubpages[NS_TEMPLATE] = true;

# <translate nowrap><!--T:14--> etc.</translate>

Disabling for a namespace

Disable subpages in a namespace (where it is enabled by default). For example NS_TALK has subpages enabled by default in MediaWiki. To disable them, set false:

$wgNamespacesWithSubpages[NS_TALK] = false;

Default value

The default of this setting has changed over the years. To be sure which one applies to your wiki check this setting in "DefaultSettings.php".
