Re: qlalchemy.exc.OperationalError: pgadmin4 startup error after upgrade version to v427

Yes, I did that one but is there a way to recover or restore all content from that backup?

Hi,
It's a SQLite database problem, so you can do following:
- Take the backup of the 'pgadmin4.db' file and then delete it.
- Restart the pgAdmin4
Thanks,Khushboo
