RHEL 6.5. When I installed Dashboard, I made the change to ALLOWED_HOSTS to add my system's name. When I try to login in, both Chrome and IE give me "an unexpected error has occurred". I've tried both FQDN and just the canonical name. I have no idea what's going on. Can anybody help????

The /var/log/httpd/error_log shows me:
