Title
Failed to update database "master" because the database is read-only -
Description
In IMOD, you may get this error when attempting to run a sync :[810143] Database error 3906: Failed to update database "master" because the database is read-only
-
Cause
The sync editor is connected directly to the database, instead of connected via the app server.
You can identify which type of connection - in the Sync editor at the very top where you see the connection details (beside 'Synchronization Editor') there will be a long string of numbers and letters, a database reference and port 3342.
When connected correctly via the app server you will see your app server address here. -
Resolution
Connect the sync editor via the App server instead of directly to the database.
