I encountered the same difficulties as Ralph to install the Shairtunes2 plugin. I had first installed the one you recommend in your interface (disaster123 version). It does not work (can’t be loaded). I tried to install the version of Philippe (fork). After activating it and restarting the server, it does not appear in the functional plugin and remains in the third-party plugin list not activated. In your answer to Ralph, you say there must be a conflict between the old version of disaster123 and the version of Philippe.
So I would like to uninstall my current server to go back on a clean installation and redo the manipulation without having previously installed Shairtunes2 version disaster123. How can i uninstall the squeezebox server from Max2Play?
