You need to edit the user group permissions of which user is a part of,
Go to Server Settings--> Users --> Roles
Under the Permission and click on Edit
select the Allowed permission as like above and click on remove button --> Click Ok and Apply
HI,We tried this and it is working fine.But i do not understand why we need dashboard read and read/write setting.Initially i thought if we set the setting as read then we can not store the dashboards on appmon server.But it did not worked as expected so i have tried the approach that you have suggested above.
