The error you're seeing — "Unknown type 'TransferredOwnership'" — usually happens when there's a mismatch between the Carbonio web client and the backend after an upgrade. Even though all services are running, the web client might not be fully updated or synced with the server. Try clearing your browser cache or using incognito mode first. If that doesn’t help, make sure the web client and mailbox versions match by running zmcontrol -v. You may also need to reinstall or update the web client part to fix missing or outdated files. Check the logs in removed link for more details.

Carbonio Web Client Validation Error: Unknown type 'TransferredOwnership' after Installation/Upgrade

I am encountering a persistent validation error in the Carbonio Web Client interface, specifically when attempting to load the conversation view or the notifications area. The error occurs despite all core Carbonio services showing as Running when checked with zmcontrol status.

1. Error Message: The error displayed in the Web Client console/log is:

Validation error (UnknownType@GetNotifications/notifications) - Unknown type 'TransferredOwnership'

This suggests an inconsistency with a data type related to sharing or files features.

2. System Status (All services are running):
