How to fix the You do not have the roles required to access this portlet message

There will be times where you want to configure the visualization permissions for a portlet.

To remove this warning, you must access the portal-ext.properties

and add (or edit) the next line:

layout.show.portlet.access.denied=false

Restart the server and you're done!
