Is this the first time you’ve seen this error?:
yes
Can you reliably replicate it? (If so, please outline steps):
The issue you are facing:
I lost my data directory and the backup during a manual upgrade (by being stupid)
what is the best way to proceed?
I created a data dir to replace it and that got populated like this:
http://paste.debian.net/933528/
I cannot log in to the browser though, the login button does not react at all.
Not sure the failure to log into the browser and the new data dir are even connected.
