i had installed keystone and then created users and servcies in keystone, then i had installed horizon dashboard and configured it but when i am trying to logon to keystone b correct credentials it is giving me error

something went wrong an unexpected error had occurred.Try refreshing the page.If that does not help try contacting your local administrator

Below are the apache logs which i think can be useful, (in /var/log/keystone i am not getting any logs):
