Allow users to override parameters

Dear Users,
I have some troubles to enable one user to use "Override All Parameters"
under "Puppet classes" page.
The button is available but when he clicks it, it appears a warning page:
"Puppetclass Not Found
Please try to update your request"

For me , I'm the admin, that button works fine.
And if I enable the override the user can modify the parameters.

So I would like to enable the user to enable the override by himself: which
type of permission should I give to him?

Thank you very much.

Luca

One update,
I enabled the user to override from each class but that button still
doesn't work.
Anyway at this point it is not a big issue.
