The Return To Safety Link on the 403 page goes here:
http://localhost:9000/admin/repository-view
For users who do not have access to management, this immediately redirects back to the 403.
This results in making the link appear to not do anything.
This probably should go to the home/index page rather than the management page.
Alternatively, this coudl check permissions and if they have access to management then provide a link to that URL and otherwise provide a home/index link.
