All good. The work around is pretty simple and got me going again! Looks like there may be some higher priority issues on the forum here to deal with first. Either way, thanks for the addon! It is doing exactly what I was looking for! If I get a chance to look as well, I'll see what PHP I remember and try a few things / suggest a fix.

I had the same problem today. Looks like the code generating that page iterates over configured groups, but on initial install that config is empty (the buttons are created inside the loop). If you create a basic groups file it seems to fix it. Open a terminal from unraid and edit the /boot/config/plugins/disklocation/groups.json file and add this: { "1": { "group_name": "Group A", "group_color": "AA2D2F", "tray_width": "400", "tray_height": "70", "grid_columns": "8", "grid_rows": "1", "disk_tray_direction": "v", "grid_count": "row", "tray_direction": "1", "tray_start_num": "1", } }
