Why do I get an “Operation must use an updateable query” error when trying to use SuperInvoice?
This is a common HTTP 500 error encountered when setting up an Access Database. All it means is the folder you have uploaded the SuperInvoice database to does not have the proper read/write permissions. Double check that you have uploaded the database your host set up specifically for databases. Sometimes hosts forget to give your database folder the proper permissions and this may be the case as well. Contact your host and verify your database folder has read/write permissions to modify the database.
