Access problem...(silly problem)

Checking your apache log, it contain: 
[Thu Mar 04 19:22:30 2010] [error] [client 127.0.0.1] (13)Permission denied: access to /index.html denied

Have you check the directory permissions? just type:
$chmod -R 755 /path/to/your/htdocs

;)  It should resolve your problem.
