Today suddenly in our production environment we got an error while opening any building block of any publication.
The error is:
Class does not support Automation or does not support expected interface.
If the error was specific to a particular publication I could have narrowed it down but currently the issue is for all the publications.
The issue was resolved by restarting all the services but I really need to know the cause for it.
Event viewer logged the following:
Unable to get list of SDL Tridion Content Manager items. Class does not support Automation or does not support expected interface
Error Code: 0x1AE (430)
Call stack: Folder.GetListItems
