403 Forbidden Error

Hey team,

I have build a new package as you have taught in your demo video.
Everything is working fine.
I am facing only one issue while accessing installer.php after uploading it to my domain.
Here is my link to installer.php

http://www.governmentjobszone.com/installer.php

I am getting this error.
“Forbidden

You don’t have permission to access /installer.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.”

I have tried changing the permission ti 755 and even 777 but still no luck.
Also i tried uploading test.html that test.html is accessible only the installer.php is not accessible.
Can anyone please help me out with this.
Thanks in advance.
