+# Troubleshooting
+
+## Getting logs
+
+MMX stores logs in `/var/log/mmx`.
+
+## No agent on the Web UI
+
+MMX stores some of its information in `/etc/mmx`.
+
+If you have some troubles getting it to work (for example, following the rename of `Controller` to `Device.Wifi.DataElements`), remove the configuration from the overlay and reboot:
+```
+rm -rf /overlay/upper/etc/mmx
+reboot
+```
