While saving the portal case in portal login, getting the error "Operand type clash: int is incompatible with uniqueidentifier".Please any help on this.
The reason of this issue is in the "Change log" that is enabled for the "Case" object and the out-of-the-box problem that starts to occur when creating the case ("Operand type clash: int is incompatible with uniqueidentifier"). To fix this issue please enable operation permissions for the "Type of Object Modification" object and add rights for portal users and regular users and also add this object to the "List of object available for portal users" lookup.
