I want to install new themes on Ubuntu 11.10, so I went to the Internet and followed the instructions to how to install new themes. I've installed gnome-tweak-tool, the Ubuntu shell user extension and everything else that I needed. But after I installed everything and restarted GNOME Shell, I went into the Advanced Settings (GNOME Tweak Tool) and the shell extensions tab is blank like before the installation. Also, in the theme tab, the shell theme option it says could not list shell extensions.

Just to make sure - Did the instructions you followed involve extracting the theme to /usr/share/themes? If not you can find a more detailed description of how to install a theme in 11.10 here.
