After upgrade from 2.5.3 to 2.5.5 all things are lost


Today I updated my system from 2.5.3 to 2.5.5. Now all things are lost. After a reboot all things are in my inbox. Do you have any idea what I can do? The items are still available. Only the things are away. I haven’t a actual backup. That’s very strange.

PS: i could restore a jsondb backup file. But do you have any idea why that happen ?

From the documentation: ....but you should **stop openHAB** and perform a backup first.
