I was having the same error as Alistar – after upgrading to Big Sur 11.0.1 on my MacBook Air (2017), Manager does not open and gives the same error as Alistar described above.
Following this thread, I downloaded the most updated version of Manager (Mac | Manager), unzipped it (ManagerServer-Mac-x64), then opened Terminal and entered the command as suggested above (./ManagerServer), but the Terminal sais:
-bash: ./ManagerServer: No such file or directory
I also tried with:
chmod a+x ManagerServer
chmod: ManagerServer: No such file or directory
Then I downloaded the Manager version from the front page of manager.io in a classic way, I opened the programme, but when I opened the last backup from my company’s data (add business, import business), it sais:
This business database is not valid
Manager data is stored in SQLite database. However it appears the file you are attempting to open is not a SQLite database.
What am I doing wrong?
I’m really worried, as it seems I have tried everything by now – and I tried several times.
Thanks for any help!
If you can open Manager in Big Sur, you should not have to import your business. Your data file should still be in the same place as it was in your application data folder. The business should appear on the Businesses page when you first launch Manager.
Why did you try to import a backup of your business?
It’s because the earlier version of Manager did not open at all after I upgraded to Big Sur (the same error such as Alistar had – image in the discussion above). So I had to download the new version of Manager, but this does not open the backup file from the old version.
Is there a (older) version of Manager available which opens old backup file, which I could then convert to SQLite?
Interestingly, the previous attempts to import the backup file are still visible on the business page and when opening them, the old kind of error appears. Could this be a problem that replacing an old version with a new one does not actually erase all the files/data in the Applications folder? Anyone has any ideas? Thank you so much in advance.
Nothing ever erases any file in the application data folder. Those files are not the program. They are accounting data files for businesses and a few housekeeping files. See Manage application data folder contents | Manager to understand the application data folder.
@Inline, can you please be more specific about what triggers the crash? You wrote, “With me is crashing by simply re-typing a customer address….” Exactly when does the crash happen? As you type? When you click Create? Or at some other point?
Also, it looks like you are using dark mode. What happens if you use light mode? (I ask because, when dark mode was first introduced, there were some problems related specifically to it.)
