Plesk admin can decide what operations the client can perform and what operations he/she should not be able to perform. To edit the client’s permissions for operations:
Click the Permissions button on the Client Home page. The Client permissions page will appear displaying the list of permissions for all available operations:
In order to allow (forbid) the client to perform a specific operation, check (uncheck) the corresponding checkbox.
Allow performing operations of managing scheduler and system access only to trusted clients as these operations must be performed with great care and can have most serious effects on the system.
When you are done editing, click Update. Clicking Up will discard all changes you made and return you to the Client preferences page.
