Summary

When a user tries to access a Confluence page that they don't have access to, they are directed to '404 Oops, you've found a dead link' error instead of a Permission Denied or a more useful error. This also affects Anonymous users who don't have access to a page and Anonymous access is enabled in the instance.

2. Let a user who doesn't have access to the page to access the direct URL of the page created on Step 1
