Please Help Me with This Urgently…Please

Can you give some more information about the error?

What version and edition are you using?
What causes the error?
What changes have been made since the last time it worked?

I have installed the latest desktop addition. The last time it worked fine was when i made an input of number of purchase invoices.

The cause of error is unknown to me. Earlier I was using windows 7 and the backup file was imported by the manager well. From the time I started using windows 10, the backup file couldn’t be imported by the software. Hence, I ended up using the backup file it self.

If anybody at all could help me please. Thanks

What version of Manager were you using in Windows 7?

You said the last time you used it you entered purchase invoices - what version was this?

You answers are a bit confused and it is difficult to follow the steps you have taken

The version is 20.2.1(Desktp)

The error indicates SQLite database being corrupted. Do you have a working backup of the business?

Yes I do. But that is about 5 months old.

My mistake was I didn’t do backup all these months as everything was going pretty smooth and never faced bugs or related all the way from the very first time I started using the software.

I cannot afford to loose the data from the past 5 months approximately. Please help me out with this issue. Thanks

If you are using desktop edition, you absolutely need to make regular backups. You can also move the entire application data folder into Dropbox or similar which will do backups for you automatically.

See: https://www.manager.io/guides/10348

It’s very rare to corrupt SQLite database but if you corrupt one, it’s usually too expensive to repair. Perhaps have a look on the internet how to repair corrupted SQLite database but usually there will be data loss one way or another.
