Theme administration

All - or most of the - theme related settings, are located in the admin's Appearance section.

The appearance menu

From this page, it's possible to enable and disable themes. Site builders can even install themes using a URL or by uploading a theme archive (tar tgz gz bz2 zip). From this page, a theme can be set as default user-facing theme using the Set as default button which appears right from the screenshot (this button won't appear for the theme that is currently set as the default theme).

A theme that is installed won't - by default - appear in the front-end, unless it's set as the default theme.

At the bottom of the page, the administration theme can be switched.
