Open Stack

Hello,
I have successfully installed Openstack (icehouse) in my physical machine
using Devstack.
But when i try to access the Dashboard using my web navigator i have the
following error :
Internal Server Error

The server encountered an internal error or misconfiguration and was unable
to complete your request.

Please contact the server administrator at [no address given] to inform
them of the time this error occurred, and the actions you performed just
before this error.

More information about this error may be available in the server error log.

Any idea to resolve this problem please ...
Best Regards
HASSAN Karim
