Public Annoucenment Service link under Confluence Administration while logged as admin user is on redirect loop

The "Public Announcement Service" link under Confluence Administration is broken when clicked as a user on the administrators group.
As a sysadmin user, the link opens okay.

Steps to reproduce:

• Log in on a JIRA+Confluence instance as a administrator user.
• Go to Confluence Admin.
• Scroll down the page and click the Public Annoucenment Service link.
