Then that isn’t a full backup. If all we are talking about is openHAB, using sudo openhab-cli backup will capture all of your OH configs.
Assuming that’s the case, the bigger question would be how did it get corrupted in the first place?
The most likely place such a setting would be stored, assuming it’s not buried in a .kar file somewhere, is userdata/etc. You can compare the contents of those files with the with the default ones here and here.
Somehow all that seems ormal and still i don’t get the official plugins… somethng extremely strange is broken at my side… Most probably I will really have to go through a fresh install…
(Sometimes I wish I never changed to OH 4… with OH3 everything was running smooth :-))
