We are currently playing around with the self-managed version of Enterprise Search (7.9.1). When trying to delete an engine, it does not work and shows the following error without any further information:
This error also occurs when trying to turn off Usage data in Settings
What could be the cause of these issues? I can't seem to find anything in the logs. I checked:
- app-server.log
- system.log
- worker.log
- stats.log
Thanks
