Multiple errors on image update

[ptruman]

I was using 10.8.5 and spotted the update - updated image and left it 2 days.

Tried to login, and found (from the error messages) I can authenticate, but am receiving multiple errors about MQTT and then PHP errors. Reverted to 10.8.5 and all is well again. I don't appear to have suffered any data loss - but if there is an upgrade path from 10.8.5 to "latest" is it published anywhere?

Screenshot available if requested.

Right, fixed this.
Even though MQTT_ENABLED is set to false, the code is still expecting values
Set MQTT_CLIENTID to emoncms
Set MQTT_PORT to 1883

Docker image will then start.

PHP errors are "Session"/header related and caused because the missing MQTT variables spit out an error to HTTP before anything else....
