Installation Issues

If you get 'directory access not allowed', maybe your apache config doesn't see index.php as a valid index file.
If you type http://localhost/citest/index.php, does it work?

A blank page is usually caused by a syntax error in the code, with error_reporting and/or display_errors switched off in php.ini, so you should check that as well.
On a development machine, it's wise to enable all error reporting you can find, to make sure no errors remain undetected.
