Please advise 
This is almost certainly either a webserver configuration issue, or a filesystem permissions issue. You may find more details in your webserver error log, but more likely than not the message there will be equally terse.
The key thing to be looking for is to ensure that the user which is running the webserver is able to read and serve out the static files within that directory.
If you can share your apache configuration as well as the ownership, group and permissions for the public directory and contents on your filesystem, we may be able to spot the problem.
