Install Completes but Site not Available

Install completed successfully but http://localhost/gibbon/ produces a blank screen. Other webapps such as joomla and Adminer work fine.
During install of the standard Gibbon download I selected testing of new features to be OFF.

“Congratulations, your installation is complete. Feel free to go to your Gibbon homepage and login with the username and password you created.”
