Seems any change sends the same error to the browser, so probably related to #951

GitMate.io thinks possibly related issues are #10333 (Admin can not change user password), #2568 (user can't change language in personal settings), #1874 (Changing password doesn't work for non-admin users), #5399 (Group admin cannot change settings in user management), and #2743 (Personal Settings - User cannot change language. Missing file.).

Does this error still occur? If so please edit your post and update the issue template. It's much easier to reproduce a problem with the issue template. Can you describe the new email address a bit? Is it a valid email?
