I too am looking for a way to get this back working. I started out in the Komga discord where the directions were to:
I run Komga on unraid in a docker, so to update to 1.0 I just need to:
1) back up my config folder
2) change the port on the docker itself from 8080 to 25600
3) change my SWAG reverse proxy set up
I have a back up of the config folder I changed the port numbers (I even edited the template in /boot/config/plugins/dockerMan/templates-user to make sure it is using port 25600) and I made sure I was updated to the latest version.
Still no UI and here is the log file:
As I mentioned, I still have the backup before I did anything so, I can replace any files. If anyone has any suggestions, please let me know. Thanks
