Main Settings / General Settings / Basic Customization / Controls, Filters & Checks / Entities editing at the same time
You can select here if Classter is going to forbid or warn end users from modifying an entity when another user also is editing the same entity.
The options are:
(a) No Check
(b) Warning , i.e. Classter will just warn the user if this happens but it will allow the end user to save any change
(c) Forbid , i.e. Classter will not allow the end user to save the entity when this entity is already being edited by another user at the same time.
Setting – > Active -> Warning (Figure 1)

*FYI: When the setting is inactive the default value is set to Warning.
