Vienna lost all subscriptions and cannot add new ones

[allamistakeo]

Hi,

Vienna suddenly stopped working. When I launch it, no window shows up. I press CMD+1 to bring the main window, and it is empty; all my subscriptions are gone. When I try to add a new subscription, after entering the feed URL, clicking on the button to subscribe doesn't do anything (the dialog remains open).

I have tried re-installing Vienna, as well as restoring the folder ~/Library/Application Support/Vienna from Time Machine, but nothing works.

Console shows an avalanche of error messages from Vienna that look like the following:

Any ideas?

The only thing that might have changed since it last worked is a macOS patch. I'm on 10.11.6 (15G22004).

Thanks in advance for your help

It is likely to be a corrupt database. Try to go back even further in your TimeMachine backup.

Thanks for your suggestion.

I restored all the way back to a time when I am sure it was working, and it hasn't solved the issue.

In fact, if I just completely trash the folder ~/Library/Application Support/Vienna and restart Vienna to re-create the folder and start with a fresh database, the main window still doesn't open on launch, the database is still empty, I'm still unable to add new subscriptions, and I'm still getting the same errors in the Console. So, it cannot be due to a corrupt database, unless Vienna creates a corrupt database in the first place.

Are there any other folders and files that Vienna creates that I might need to trash to really start fresh?

Worth mentioning: I am not able to reproduce this with a different local user that had never launched Vienna before.

delete ~/Library/Preferences/uk.co.opencommunity.vienna2.plist
delete ~/Library/Caches/uk.co.opencommunity.vienna2

Empty trash.

(and remove the freshly created Vienna folder in ~/Library/Application support, just to be on the safe side)

For good measure, log out and log back in. Launch Vienna. Hopefully you are successful. Then quit Vienna, and replace the Vienna folder with the (working) back up. Launch it again. Knock on wood etc.

[allamistakeo]

delete ~/Library/Preferences/uk.co.opencommunity.vienna2.plist

This single step turned out to be sufficient to fix the issue.

Thanks for your support!
