Main Settings / General Settings / Student/Parents Portal / Personal Data Management / Allow End Users to Change Profile Data
Here, you define whether users will have the right to edit profile data.
Example in teacher’s portal
Setting -> Active
The user can click on the Edit Profile option and edit his/her profile details, as shown below
Setting -> Inactive
When the setting is inactive then, users cannot edit their personal data, because “Edit Profile Entries” option is missing
