Confluence disables and hides certain special features. Learn how to turn them on.Using a hidden administrative interface to turn dark features on and off

So-called "dark features" are simply system configuration options that are hidden from the normal Confluence Administration menus. Dark features are hidden (though accessible) because changing them may result in major disruptions to the Confluence environment. However, there may be scenarios where one or more of these options should be disabled or enabled. Typically, this is only done by request from Atlassian, maker of Confluence, during troubleshooting, compatibility testing, or for re-enabling a legacy option.  Dark features are also called "labs features" or "hidden options."Only a System Administrator can enable or disable dark features.

Determine if you have System Administrator privileges

In order to access and change dark features, you must be a System Administrator.

Visit the special dark features URL

Enter the following URL postfix into your browser window:    

For example (on a locally-running Confluence instance), the full URL is:

Disable or enable a dark feature

There are two lists of dark features: System Property Dark Features and Site Dark Features. In order to change the former, you must restart the server with or without one of the features using a special command (beyond the purview of this How-To entry).

To change a Site Dark Feature, you must either click the "remove" button (to disable) or manually type a dark feature property name into the text box (to enable)

Use h4 for section headings

If you don't want numbers in the section headings, simply remove the "numbered" class from this block.

Note/Tip/Warning/Info blocks below are collapsed by default. If you want to use any of these, try to keep to just one per page. You may use two if necessary, but in general, try to limit these.
