Beginners Question about MultiLibrary Plugin

Hello,

I'm very new to the SqueezboxServer and in order to seperate my music files into seperate Librarys I found the MultLibraryPlugin. I tried to install everything as told on the Wiki and the Example "Setup Kids Room", but I can't find no Button for "Create new library" and the other settings under Extras/Multilibrary ...

The Squeezboxserver ( 7.6.1 ) is running on a qnap-nas.

Perhaps anybody can help me???

Thanks a lot ...
