OperationalError: unable to open database file

Most likely an InstallationIssue. An incorrect [trac] database string is the simplest cause of the issue. Another possibility is that you are out of disk space, or that the database file permissions are incorrect. See OperationalError: unable to open database file?noquickjump=1.
