Variables have changed in version 4.8.0.x.
How to update?
In Docker UI:
- Registry > search for image name you want to update > Download image
- Stop container
- Select container > Edit ; go to Environment tab and rename old variables to new one (check the Overview tab)
- Save
- Select container > Action > Clear
- Start container
You'll probably need to wait a few minutes for everything to set up then visit your FireFly page and finish the upgrade.
