Hi Jan,
could you try the latest Max2Play Image based on Debian Jessie (for RPi 2/3) from our Download Page and do the following steps:
– install MPD-Addon with Installer for MPD and AMPACHE on Settings/Reboot Page (http://shop.max2play.com/media/downloadable/beta/ampache.tar)
– update to latest Beta of Max2Play on Settings/Reboot Page
– install Ampache by clicking „install“ on MPD Player Page
Now you should be able to access the Ampache Webinterface. Activate „Create Database User“ on first step of configuration and set a Password for the ampache User and create the Config-File (use „max2play“ as root password for the database) -> finished.
