Error: SQLITE_CANTOPEN: unable to open database file

I logged into Tropy today to continue working and I got the following error message “Error: SQLITE_CANTOPEN: unable to open database file”. Does anyone know what has gone wrong and if I can fix it?

Most likely, this error means that Tropy cannot open your project file: for example if the file permissions have changed or if the file was damaged while Tropy was closed. Where is your project file located? Is it possible that the permissions on the disk have changed recently?

It’s also possible that this error is not related to your project file, but to the ontology database, if you could attach your tropy.log file here (see Help -> Show log files), we might be able to tell what’s wrong exactly.
