AEM 6.5 Root node is not accessible
Hi,
When accessing the URL http://server:port/crx/explorer/nodetypes/index.jsp as admin I get the following error message:
Unable to retrieve node type manager probably due to insufficiant rights. Please login as a more priviledged user.
javax.jcr.AccessDeniedException: Root node is not accessible.
The etc/key access tab has the following setting. Please advice.

Thanks,
Leena
