You Cant Display this Ticket MC3

The client has suddenly received this error on MC3.
There have been no new users or changes to user access levels.
Anyone here have this error or any help on how to handle this issue?

It’s about role permissions for can’t access other waiters tickets.

thanks @Jesse let me check the settings

We recently added that to mc3. So check your role permissions and allow waiters to access others tickets if you want them too.
