The application attempted to open a SQLite database which is read only and cannot be edited.
This error can come from a number of conditions including the file being marked as read only, insufficient write permissions, read only file system, corrupt files, interference from antivirus software. The root cause can be something which reports this error even though it can seem unrelated, such as a temporary file being deleted immediately after creation.
If possible locate the file and ensure that the user has the ability to edit it, keeping in mind that if the file may be accessed by a service and is using its credentials. Otherwise, contact Admin Arsenal support for help in locating the root cause.
