Parâmetros de configuração

This page is a translated version of the page Manual:Configuration settings and the translation is 1% complete.
Starting with MediaWiki 1.39 the configuration settings are based on MainConfigSchema.php.

This is an index of all supported configuration settings based on the DefaultSettings.php file.

Never edit DefaultSettings.php; copy appropriate lines to LocalSettings.php instead and amend them as appropriate.

If you cannot find a configuration setting here, see if it is defined in DefaultSettings.php. The variable should have some documentation there.

Settings removed in versions of MediaWiki prior to 1.31 are no longer listed here. Please use the search box to find the relevant manual page (e.g. Manual:$wgAllowAnonymousMinor).
