Hi All,

The error is displayed intermittently.

Can anyone please help to resolve this issue

Did you change something in KM configuration ?

Regarding the error, perhaps check command group:

System Admin --> System configuration

Knowledge Management -> Content management

User Interface -> Settings -> Layout set

Search for "ConsumerTreeList" ==> note that this layout set uses [Layout Controller: MenuTreeListLayoutController ]

But then check for example the ConsumerMenu (in Collection Renderer). There you have Mass Command Group: ConsumerMenuGroup --> clic on it. As command list you should have: [ConsumerViewGroup,ConsumerFolderGroup,ConsumerGotoGroup,ConsumerSearchGroup] in Command List

We get quite the same error after an upgrade. In the command list we put 2 commas between 2 commands groups.

If you go in edit mode, just change the description and save if there is a problem the system gives an error.

Good luck.

Resolved. Certain hot deployments were done which wanted server restart. After server restart, it worked fine.
