Removing "This is an unversioned page"

You need to edit the Space Stylesheet and add the following:

#sv-infoline-container { display: none!important; }
#action-menu-link-sv-contentaction-section { display: none!important; }

By Default Scroll Versions will show version information about pages.  This is the area highlighted in yellow.  This is not used by the Documentation Toolkit and can be hidden.
The instructions below show you how to hide this.

NOTE: You will only see this version information if Scroll Versions is installed.

To edit the Stylesheet click on Browse and then on "Space Admin".

Now click on Stypesheet in the Side Bar

You will see a screen similar to the one below.  Click on Edit.

Key in the following information:

#sv-infoline-container { display: none!important; }
#action-menu-link-sv-contentaction-section { display: none!important; }

and then click on Save

The screen will then look similar to the below.

When you browse this space again the "This is an unversioned page" message will no longer be there.
