@RogerO sorry for the delay responding, if the files are in dist-config I'm not quite certain how it's going wrong!
On startup it copies those files from /opt/reactor/dist-config -> /config/reactor if the /config/reactor directory doesn't exist.
If it can't find logging.yaml that steps failed and stopping the addon, deleting /config/reactor and restarting it should get it to retry.
The addon logs of that first start would hopefully contain any error messages.
