Suggestion
Improve the messaging for the restricted page. This is really useful where multiple spaces are enabled with Anonymous access. So when users access these pages without logging and navigate to another space (which is not enabled with Anonymous access), they are under impression that they do not have access to pages but actually since they are not logged in they see this error message.

So, it will be good to improve the page/space restriction message where it prompts to login to the account.

Suggestion
Improve the messaging for the restricted page for licensed users.
