Thanks Euguene. Will try and update. Really great help. 
shifted contents to domain name folder from wp folder inside it. That worked. Thanks for your time
In port option, I use * for host. I event tried using local host there. But that too didn't work. I am using a VPS from RamNode if that helps. 
I should have phrased it better. It is my website that is giving 403 after setting through Ajenti. Thanks for the reply. 

Checked, I am using PHP FASTCGI,
The screen shots are different from the latest version.
The only thing I did was follow the install Ajenti for Debian commands on your website, and the working site gave 502. :(
